You are given a matrix full of numbers who happen to be very shy. Write a MATLAB function that will put a square of zeros around each term in the matrix, thus giving them the privacy and space they desire. This should include a border of zeros around the outside of the matrix.
For example, if your input matrix is magic(3):
[8 1 6 3 5 7 4 9 2]
your output will be:
[0 0 0 0 0 0 0 0 8 0 1 0 6 0 0 0 0 0 0 0 0 0 3 0 5 0 7 0 0 0 0 0 0 0 0 0 4 0 9 0 2 0 0 0 0 0 0 0 0]
Please help them out, but do so quietly; they don't like the attention very much.
dyadup funciton is not supported?!
I'd never heard of it, but you are correct: it does exactly what this problem asks. It's part of the wavelet toolbox, which I guess isn't included in Cody.
Always a chance to learn new matlab functions.
"find" combine with "accumarray" function so naturally,couldn't even tell which is which.really good work!
