Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct

matrices, use brackets instead of parentheses.

this is the line with problems

f = figure ('position', [0, 0] scrz(3),scrz(4));

Answer 1

There is a comma missing:

f = figure ('position', [0, 0]  scrz(3),scrz(4));
%                             ^^ missing a comma

However, I think you probably mean to say:

f = figure ('position', [0, 0, scrz(3), scrz(4)]);
