Try using M[i,2 instead to examine the i th row of the third column. At
present you are "extracting" a 90000 x 1 vector at each step. BTW,
shouldn't the range be from 1 to n (assuming base zero) ? It will fail if
the first row is zero. You may also need to "declare" the size of the M
array by M[rows(M),3)=0 in the second line.

Subject: [mathcad] Program execution time
Am wondering about execution time on the data clean up routine below.
On a test matrix with 1000 rows, it executes in a blink of an eye.
But on the actual data set with 90000 rows (4 cols), it takes somewhere
between 1/2 hr to 1 hr.

Any comments on the cause of the long execution time and suggestions on work
around?
Thanks
