Map matrix element to string

Question

I would like to map numeric output from a matrix to a string.

Given

compute=[ 7, 4, 3; 3, 4, 7]

how can one obtain a string mappin

Answer 1

I assume you have the map in a form of a cell array

>> map{3} = 'Jog';
>> map{4} = 'Walk';
>> map{7} = 'Run';

Now use the map

map( compute )

will give you a cell array of strings
