Only 1st layer of a 3D Matrix.

I have this code and I am having issues trying to figure out how to just display the 1st layer with it's own variable.

Also another variable that displays the absolute central colum.

Thank you.

A = ones(5,5,3).*reshape(1:3,1,1,3)

For layer 1:

A(:,:,1)

For layer i:

A(:,:,i)

For the central column:

A(3,3,:)

Thank you.

For the central colum...how to full central in to 1 x 5 matrix so the out put would be

1
1
1
1
1

2
2
2
2

3
3
3
3

Do you want to fill the centeral column?

[Nicholas Deosaran]

Yes, i am sorry for not explaing well

[Nicholas Deosaran]

Any idea on how to do it ?

This command:

A(3,3,:) = 1;

fills the central column with 1

ItsOwnVariable = A(:,:,1);

AnotherVariable = squeeze(abs(A(:,round(end/2),:));   %absolute, central ?
