I have an array that might look like this:
ANOVAInputMatrixValuesArray = [[ 0.96488889, 0.73641667, 0.67521429, 0.592875,
0.53172222], [ 0.78008333, 0.59381
I might be too late to answer this question, but wanted to share my input for the benefit of the community. For this example, let me call your matrix 'ANOVA', and I am assuming you're just trying to remove rows from this matrix with 0's only in the 5th column.
indx = []
for i in range(len(ANOVA)):
if int(ANOVA[i,4]) == int(0):
indx.append(i)
ANOVA = [x for x in ANOVA if not x in indx]
