There is sometimes confusion over how to select scattered elements from a matrix. For example, suppose you want to extract the (2,1), (3,2), and (4,4) elements from A. Scattered elements in a matrix. How would we notate this desired output? The expression A([2 3 4], [1 2 4]...

two matrices into a larger matrix.(a) We extract elements from a matrix to create a new matrix, just like with vectors. Recall that with a vector v of size 5, if I wanted a new vector u containing the 1st, 4th and 5th elements, I type: u=v([1 4 5]). We use the same idea...
