Write a function matsort to sort all of the values in a matrix

(decide whether the sorted values are stored by row or by column). It

will receive one matrix argument and return a sorted matrix. Do this

without loops, using the built-in functions sort and reshape. For

example:

>> mat

mat =

4 5 2

1 3 6

7 8 4

9 1 5

>> matsort(mat)

ans =

1 4 6

1 4 7

2 5 8

3 5 9

matsort.m

function outmat = matsort(mat)

% Sorts ALL of the values in a matrix and

% then stores them column-wise

% Format of call: matsort(matrix)

% Returns a matrix, sorted and stored by columns

[r c] = size(mat);

vec = reshape(mat, 1, r*c);

vs = sort(vec);

outmat = reshape(vs,r,c);
