How do I get the value at a particular index?

So I have indices corresponding to values that I want. Is there a MATLAB function that would allow me to output the values when I input the indices of those values?

Yes the techniques there are good, except I would not use the diag() one

Hi
Consider A as the matrix, and x as indices, then
Values = A(x)
In case you need value of a 2-D matrix, define 'rowMatrix' which has the row indices and 'colMatrix' which has corresponding column indices, then
Values = A(rowMatrix, colMatrix)
