MATLAB: I have Parse error at ‘<' :usage might be invalid syntax

parse error

Here is my code

for j < maxc

Best Answer

You are using C or C++ syntax. MATLAB syntax is either

for variable = expression

while expression

You should probably be using

for j = 1 : maxc

or possibly

for j = 1 : maxc - 1

b[j]=a;

This line should be

b(j)=a;

Also, indexing should start from 1. Be careful with that.

MATLAB: Parse error: usage might be invalid MATLAB syntax

You included the answers in the file, and MATLAB is trying to interpret them as commands. My guess is that you don't need the diary commands either, so a working file would look like this:

A = [1,2,3,4];
B = [4,3,2,1];
C = (A+B);
disp(C);
D = (sin(A));
disp(D);
