Learn more about matlab MATLAB A=[1, 3,4] I want to print size of A is length(A) and A is print(A , length(A)) 2 Answers Sorted by: 3 Use two single quotation marks. See the docs for formatting strings, btw this concept is known as an escape character (to help you google such things in the future). command = sprintf ('%s ', varargin {1}, ' (''', varargin {2}, ''')') Although I think you might preferAccepted Answer. Of course there is no correct answer because these are binary floating point values, but here is one solution that gives the "least unexpected" output. It assumes double values and upto 15 significant figures. chr = reshape (sprintf ('%.14e',abs (arr)), [],numel (arr)).';Is it possible to insert variables into a string like a legend or title? For example, I'm modeling a difference equation, and I'm using for-loops to test different parameters within the equation; is it possible to plot the results where the parameter value can be displayed in a legend or title with each for-loop iteration?Numeric conversions print only the real component of complex numbers. If you specify a conversion that does not fit the data, such as a text conversion for a numeric value, MATLAB ® overrides the specified conversion, and uses %e. Example: '%s' converts pi to 3.141593e+00.

Display Formatted Text on the Block Icon. Convert the character a to an integer 97 and display it on the block icon. myvar = 'a' fprintf ('hello = %d',myvar);

disp(X) displays the value of variable X without printing the variable name. Another way to display a variable is to type its name, which displays a leading "X =" before the value. If a variable contains an empty array, disp returns without displaying anything.

Sorted by: 6. You could do it the following way: h = msgbox ( ['The result is ' num2str (MS)], 'Title of the message box') With num2str I convert the numerical result to a string, and with the square brackets I concatenate "The result is " with the result to display it in the message box.

The solve function returns a structure when you specify a single output argument and multiple outputs exist. Solve a system of equations to return the solutions in a structure array. syms u v eqns = [2*u + v == 0, u - v == 1]; S = solve (eqns, [u v]) S = struct with fields: u: 1/3 v: -2/3.The name of the variable should not matter. Not that it is "varname" in every case here. But the name might be different in the caller. Nevertheless, relying on the name is a pitfall. Better create a specific variable, which carries the name:symstr = "1 + S + S^2 + cos (S)" Display symstr as a formula without evaluating the operations by using displayFormula. S in symstr is replaced by its value. displayFormula (symstr) 1 + e 2 π i + e 2 π i 2 + cos ( e 2 π i) To evaluate the strings S and symstr as symbolic expressions, use str2sym. S = str2sym (S) S = 1.You can use the CHAR method for symbolic objects to convert them to strings and the FPRINTF function to print the strings to the screen. Here's an example: syms x y z; %# Define symbolic variables eq = 2*x+3*y+4*z; %# Create symbolic equation fprintf ('The equation for the rectifying plane is: %s = D.\n',char (eq)); And this will display the ...Description example disp (X) displays the value of variable X without printing the variable name. Another way to display a variable is to type its name, which displays a leading " X = " before the value. If a variable contains an empty array, disp returns without displaying anything. Examples collapse all Display Variable Valuessz = size(A) returns a row vector whose elements are the lengths of the corresponding dimensions of A.For example, if A is a 3-by-4 matrix, then size(A) returns the vector [3 4].. If A is a table or timetable, then size(A) returns a two-element row vector consisting of the number of rows and the number of table variables.

Description. function [y1,...,yN] = myfun (x1,...,xM) declares a function named myfun that accepts inputs x1,...,xM and returns outputs y1,...,yN. This declaration statement must be the first executable line of the function. Valid function names begin with an alphabetic character, and can contain letters, numbers, or underscores.When you specify fewer output variables than the number of outputs returned by the expression, MATLAB assigns the first N outputs to those N variables and ignores any remaining outputs. In this example, MATLAB assigns C{1,1:3} to the variables c1 , c2 , and c3 and ignores C{1,4:6} .Notice that I have a csv file and matlab gave a variable name to each column of my data. I don not want that head to be printed.You can use the CHAR method for symbolic objects to convert them to strings and the FPRINTF function to print the strings to the screen. Here's an example: syms x y z; %# Define symbolic variables eq = 2*x+3*y+4*z; %# Create symbolic equation fprintf ('The equation for the rectifying plane is: %s = D.\n',char (eq)); And this will display the ...If you are using the variable browser then at the top of the area you have the ability to change the format for that one variable (until you have close that browser on the variable), or you can look in Preferences to adjust the default used by the variable browser. Again, you will not be able to see the last meaningful digit this way.

disp(X) displays the value of variable X without printing the variable name. Another way to display a variable is to type its name, which displays a leading “X =” before the value. If a variable contains an empty array, disp returns without displaying anything.The name of the variable should not matter. Not that it is "varname" in every case here. But the name might be different in the caller. Nevertheless, relying on the name is a pitfall. Better create a specific variable, which carries the name:

Name of MAT-file, specified as a character vector or string scalar. The file name can include the full, relative, or partial path. For example, whos -file myFile.mat lists all variables in the MAT-file named myFile.mat. The whos -file filename command does not return the sizes of any MATLAB objects in file filename. Data Types: char | string.

The square root function in MATLAB is sqrt(a), where a is a numerical scalar, vector or array. The square root function returns the positive square root b of each element of the argument a, such that b x b = a.

While you can specify the precision in a formatting operator for input text (for example, in the %s operator), there is usually no reason to do so. If you specify the precision as p, and p is less than the number of characters in the input text, then the output contains only the first p characters.. Field Width. The field width in a formatting operator is a nonnegative integer …example. T = table ('Size',sz,'VariableTypes',varTypes) creates a table and preallocates space for the variables that have data types you specify. sz is a two-element numeric array, where sz (1) specifies the number of rows and sz (2) specifies the number of variables. varTypes specifies the data types of the variables. example.s = summary (T) returns a structure, s, that contains a summary of the input table or timetable. Each field of s is itself a structure that summarizes the values in the corresponding variable of T. If T is a timetable, then s also has a field that summarizes the row times of T. example. summary (A) prints a summary of the categorical array A ... s = summary (T) returns a structure, s, that contains a summary of the input table or timetable.
