I have an array that is declared global and after first definig it and using it with size [1,3] - for example - I want to resize it to be [1,2] for the next step.
Code:
> global sin
> sin= [1 2 3]
> resize sin to only have 2 columns.
Thanks for your help.

I second the general recommendation to go through a basic tutorial.
But, also, I have some suggestions/questions:
- You should not define a variable called sin. That is a MATLAB keyword for the sine function. It is poor programming practice to name variables with keywords.
- Why are you defining the variable to be global? That is almost never necessary, especially in the sorts of programs a beginner will be using.
- Your variable has 3 values. How can you make it into a size [1,2] array? Do you want to discard a value?
