Hi everyone!
I'm trying to call a m-file (I named it as 'trycall') in another m-file (I named it as 'callnow'),
in trycall I write:
y = 2x + 3;
in callnow I write:
clc
clear
x = 10;
trycall;
z = y;
this is what I get when I ran the code:
Error: File: trycall.m Line: 1 Column: 6
Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To
construct matrices, use brackets instead of parentheses.
Error in callnow (line 5)
trycall;
I save them both in the same directory (I save them in Desktop).
I don't have any idea what I do wrong. What am I supposed to do?
Any help would be appreciated. Thank you! Have a good day.

Read the error message: "Check for missing multiplication operator..."

y = 2x + 3;
2x is not a valid variable name in MATLAB, and it is not a valid way to write a number in MATLAB.
Like the error message said, "Check for missing multiplication operator"
