(mtrx) ¶Returns zigzag walk-off of the elements of mtrx. Essentially it walks the matrix in a Z-fashion.
mat = 1 4 7 2 5 8 3 6 9 then zigzag(mat) gives the output, [1 2 4 7 5 3 6 8 9], by walking as shown in the figure from pt 1 in that order of output. The argument mtrx should be a MxN matrix
An example of zagzig use:
mat = reshape(1:9,3,3); zigzag(mat) ans =[1 2 4 7 5 3 6 8 9]
