How do you convert numbers to percentages?

transMatrix = [.02 .01 0 0 .06 -.08; .03 .12 .12 0 .17 -.06; .025 .07 0 .0002 .07 -.03; 0 0 .0002 0 .05 -.02] I would like to change these numbers to percentages.

What do you mean? What are those numbers currently?

[Walter Roberson]

Percentage out of the row total? Percentage out of the column total? Percentage out of the entire matrix total?

>> P = 100 * transMatrix
P =
    2.00000    1.00000    0.00000    0.00000    6.00000   -8.00000
    3.00000   12.00000   12.00000    0.00000   17.00000   -6.00000
    2.50000    7.00000    0.00000    0.02000    7.00000   -3.00000
    0.00000    0.00000    0.02000    0.00000    5.00000   -2.00000

You can easily print them with a % symbol:

>> F = sprintf('%s\n',repmat('%8g%%',1,6));
>> fprintf(F,P.')
       2%       1%       0%       0%       6%      -8%
       3%      12%      12%       0%      17%      -6%
     2.5%       7%       0%    0.02%       7%      -3%
       0%       0%    0.02%       0%       5%      -2%
