I have a 101 by 23 matrix, where first column is the ID of persons. I want to extract each value of every person <1.5, and store them in a new matrix, SO resultant matrix should have all values <1.5 and rest can be substituted to 0.

lowscale = numData; lowscale(lowscale < 1.5) = 0;

Incorrect number of output arguments for 'pre_test_fixpt'. Expected 1, but found 2.

You show code for pre_test, but the error is about pre_test_fixpt. Have a look at how you call this function in your code.
