Yes. Add outputs to your function if variables are immediately

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.While MATLAB displays arrays according to their defined sizes and shapes, they are actually stored in memory as a single column of elements. A good way to visualize this concept is with a matrix. While the following array is displayed as a 3-by-3 matrix, MATLAB stores it as a single column made up of the columns of A appended one after the other.Here are three ways to display multiple variable values on the same line in the Command Window. Concatenate multiple character vectors together using the [] operator. Convert any numeric values to characters using the num2str function. Use disp to display the result.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.

For example, convert a signed integer to a single-precision floating-point number. x = int8 (-113); y = single (x) y = single -113.Yes. Add outputs to your function if variables are immediately needed in other functions or scripts. Otherwise, you can save any (or all) variables within a function by calling save (filename,variables) at the end of the function (for troubleshooting purposes). If you are running a script, any variables within the script are already available ...If you want to see the variables in a function workspace, then you have two main ways to achieve this: return some variables (i.e. output arguments) from a function to another workspace. use the debugging tools to view inside any workspace.
