I have a program in which I have some matrices of varying size that runs through a piece of code, for the current moment i only have two matrices. What i want to know is how would i place the matrices 'M' in a bigger matrix of zeros in a way that the values always stay in the diagonal and the rest of the matrices are zeros. So, for example if a have two matrices with size 4x4 the matrix would be a 8x8 matrix with [1:4,1:4] and [5:8,5:8] being values and the rest zeros. I want to do it in a way that i can do it for n-matrices. Here is the code i use.
dtx = -(D(1,:)-m0(2))./(v.*dn);
dty = -(D(2,:)-m0(3))./(v.*dn);
dtz = -(D(3,:)-m0(4))./(v.*dn);
M=[dt0; dtx; dty; dtz];
'Stations' is a cell array i use to store the different matrices
