The name of the variable should not matter. Not that it is "v

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.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.Learn more about matlab, precision, rounding, mat2str, num2str MATLAB I have both scalar and matrices that I want to print out to the workspace. I'm using num2str() and mat2str() but I am finding that there are some slight precision differences between using format l...If you want to get all of the output values, you will have to call answer in the following way: [out1,out2,out3] = answer (1,2); This will place the value d in out1, the value e in out2, and the value f in out3. When you do the following: answer (1,2)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} .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.If you modify a class you modify the functions of tha class. If you are working on a specific function you can set a breakpoint. The execution stops at that point leaving you in debug mode ("K" prompt in command window). Now you can execute "who" and see the variables in the function as defined up to this point.Description. 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.Read what the MATLAB documentation has to say about this: "A frequent use of the eval function is to create sets of variables such as A1, A2, ..., An, but this approach does not use the array processing power of MATLAB and is not recommended. The preferred method is to store related data in a single array"Description. 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.Copy.

Check it.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 …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};Currently, MATLAB Live Editor displays symbolic variables with subscripts, superscripts, and accents in standard mathematical notation. Hence you need to use live scripts to use the subscript functionality.I am trying to print multiple variables to the command window with accompanying text. disp does not seem to want to work, nor does fprintf. Does anyone have any idea how i can do this. I am trying to print code to look like the following, inserting variables in between text. print ('The minimum value is', minY1 (2), 'which occurs at x = ', minX);legends=compose (fmts,nums); hLg=legend (legends); saves generating and having to use sequentially-named variables and the need to edit all of them in case something changes. This way all the edits are in one place and the number, order, etc., etc., etc., ... are all independent of the code--and vice versa.There is no way to direct output to the Command Window from a live script that you run in the Live Editor.
