How to sum only a few elements in a line
Hello,
I have a matrix with the numbers 0,1 and 9
I would like to write a function that could sum each line skiping everytime
a number 9 appears
for example
[0 1 0 1 1 9 1]
the sum would be 4.
However I cannot replace 9 by 0 otherwise after the sum is done I wouldn?t
be able to distiguish which ones were real zeros and which ones were nines
replaced by zero just to sum.
Thank you very much
