Modify cells meeting some criteria

Is there a way to set all entries of the matrix which meet a given criteria to an arbitrary value?
I've got a distance matrix and want to set all cells with values greater than some threshold to NaN for graphing purposes. What I do now is a double loop but is there any function or trick which can do it for me?

RE: Modify cells meeting some criteria

Try the if function.

Two ways

1 - embedded with your normal formula:
=+if(NormalFormula<threshhold,NormalFormula,1E99)

2 - in a different sheet, referring to a cell in the original sheet that contains the formula:

i.e. in sheet 2 cell C3
=+IF(sheet1!C3<threshhold,sheet1!C3,1E99)

Sorry, I didn't make myself clear - I'm talking about a matrxi in Matlab. But thanks anyway :)
