Add a row to the bottom of A that consists of the mean of each column of A and assign the resulting matrix to B.
I am trying to add a row into an unknown matrix - the row has to consist of the mean of the columns of the unknown matrix.
Does anyone have ideas?
Thank you,
Gabe

doc mean
The last row of the matrix A is A(end,:). Then ask yourself: What would be the indexing of one row beyond "end"?

James,
thanks for your response. It helped point me in the right direction.
I worked out, "A(end+1,:)=mean(A)" which, is perfect its what I need..EXCEPT I need the resulting matrix from the (A) and, A(end+1(mean(A)), to be under the variable B.
I'm not sure how I can do that aside from saying B=ans.
I have tried many different variations, and looked everywhere and I'm getting nothing.
Do you have any suggestions?
