Suppose i have a matrix (2x4) A=[1 2 3 4;5 6 7 8] and i want to change it into this matrix [1 2;3 4;5 6;7 8]. How to do that?

A= [1 2 3 4;5 6 7 8]

Output needed

B= [1 2;3 4;5 6;7 8]

When using MATLAB you will do these kind of things quite often. Understand the order of data stored in memory:

A = [1,2,3,4;5,6,7,8]

A = 2×4

1 2 3 4 5 6 7 8

B = reshape(A.',2,4).'

B = 4×2

1 2 3 4 5 6 7 8

Answer 2

[John D'Errico]

help transpose
help reshape

Essentially, you need to learn how elements are stored in a matrix. You need to learn to manipulate the shapes of the matrices you will work with. If you don't understand this, well, then it is time to learn!

@Payel this is super basic. You're not going to get very far, very fast if you have to ask Answers volunteers every time you want to do something as simple as this. You need to learn it yourself.
