Hi,

I have an array as follow:

A = [127 77 107 148 30];

I want to convert this array as follows:

B = [127 0;77 0;107 0;148 30]

I mean, I want to split A array unequally or equally.

How can I do this?

Thanks.

Are you going to specify the number of columns to put into each row, like

columnsPerRow = [1; 6];

columnsPerRow = [1; 4; 2];

??? Otherwise how would we know? Is this your homework? Sounds like it.

The number of columns to put into each row is always changing. I want to apply this as a rule.

Something like this ?

A = [127 77 107 148 30];
B = [A(1:end-2).',zeros(numel(A)-2,1);A(end-1:end)]
B = 4×2
   127     0
    77     0
   107     0
   148    30
