What is the meaning of the symbol (') at the end of linspace?

7 views (last 30 days)
Hello everyone,
I just started learning MATLAB. I was reading the documentation to plot discrete sequences: https://au.mathworks.com/help/matlab/ref/stem.html
I tried these lines of code online:
X = linspace(0,2*pi,50)';
Y = [cos(X), 0.5*sin(X)];
What is the meaning of the symbol (') in the linspace command before (;)? I can't find documentation about it. I noticed that if I remove it I get the error: X must be same length as Y.
Any help will be appreciate it. Thanks.

I just figured it out.
This is a row vector:
linspace(0, 2*pi, 50);
This is a colum vector:
linspace(0, 2*pi, 50)';
