Another way used in MATLAB is to type the name of the variable in the command window after the variable is assigned a value; doing this will display the name of the variable also ...Print a vector with variable number of elements using sprintf. In the following code, I can print all the elements in the vector item separated by a space as. item = [123 456 789]; sprintf ('%d %d %d', item) ans = 123 456 789.fprintf ('The highest point of the mountain is : %d feet.\n', hp); Just like with the C language, if you're familiar with that. Or, if hp is a floating point number instead of an integer, use %f instead of %d: fprintf ('The highest point of the mountain is : %.2f feet.\n', hp); That is the correct behavior.If you want to create a MATLAB array of numbered symbolic variables, you can use the sym or the syms syntax. Use sym to create an array of many numbered symbolic variables. Clear the workspace. Create a row vector containing the symbolic variables a 1, …, a 10 and assign it to the MATLAB variable A. Display the variable in the MATLAB workspace.

Boolean numbers are either "TRUE" or "FALSE", represented in MATLAB by a 1 and a 0 respectively. Boolean variables in MATLAB are actually interchangable with doubles, in that boolean operators can be performed with arrays of doubles and vice versa. Any non-zero number in this case is considered "TRUE". Most of the rational operators …Print variable in new window. Learn more about new command window MATLAB.

It assumes double values and upto 15 significant figures. chr = reshape (sprintf ('%.14e',abs (arr)), [],numel (arr)).';

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.

So, if my X = 25, and I need it to display 25 ft/lb ...To create a new variable, enter the variable name in the Command Window, followed by an equal sign ( =) and the value you want to assign to the variable. For example, if you run these statements, MATLAB adds the four variables x, A , I, and C to the workspace: x = 5.71; A = [1 2 3; 4 5 6; 7 8 9]; I = besseli (x,A); C = {A A A}; To get the data type, or class, of a variable, use the “class” function. x = 100; class (x) To determine if a variable has a specified data type, use the “isa” function. tf = isa (x,'double') For a list of functions that determine if variables have specific attributes, see “is*”. You also can use the “validateattributes ...The data type (class) must be a built-in MATLAB ® numeric type. For other classes, the static rand method is not invoked. For example, rand(sz,'myclass') does not invoke myclass.rand(sz). Size arguments must have a fixed size. See Variable-Sizing Restrictions for Code Generation of Toolbox Functions (MATLAB Coder).I am running a loop, in which variables are calculated. It would be useful to be able to see the current values of these variables. It is not useful to print them, because other parts of the loop are printing a lot of text.
