print a variable in matlab

To print a variable in Matlab, you can use the disp() function. Here's an example:

main.m
x = 10;
disp(x);
17 chars
3 lines

This will output 10 in the command window. You can also concatenate strings and variables using the sprintf() function:

main.m
x = 10;
str = sprintf('The value of x is %d', x);
disp(str);
61 chars
4 lines

This will output The value of x is 10 in the command window.
