How can I convert an array to a matrix?

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.

What is the rule for when to insert a 0?

[Abdullah Türk]

There is any rule insert 0. My aim is only split the array equally or unequally. For example, I have an array as follow:

X = [100 126 35 84 39 139 90];

And, I split it as follows:

Y = [100;126 35 84 39 139 90];

I know that Y array is not work. So, Y array can be as follows:

Y = [100 0 0 0 0 0;126 35 84 39 139 90];

The important issue for me that split X array.

I mean, X array have 7 elements and I want to split it as 1 and 6 elements. Of course, 1 and 6 values can change. For example, they can be 1,4,2.

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

columnsPerRow = [1; 6];

or

columnsPerRow = [1; 4; 2];

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

[Abdullah Türk]

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
