Adding a row to an unknown matrix - the row consists of the mean value of the columns of the unknown matrix.

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

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?
