No Negatives

Write a function called genMatNoNeg that takes an array of integers called inMat and creates an ouput array that replaces all the negative numbers in inMat with zero.

Restrictions: Logic indexing should be used. Loops should not be used.

Ex:

inMat $=[$

$45-2$;

$521$;

$-3-45]$

genMatNoNeg$($ inMat $)$

produces

outMat $=$

$450$

$521$

$005$
