suppressing command window output from function calls

I have a function that calculates local time from input UTC time. The call to the function looks like this.

[dateStr, sampleLSTHr, sampleLSTMin] = UTCtoLST(dateStr, sampleTimeZone);

This function gets called many (1000s) of times as we process satellite swath data. Despite the semi-colon, with each call it triggers output to the command window.

How do I suppress that output?

Thank you.

There is a line of code inside that function that is missing a semicolon. Or else you are using fprintf() after the call to that function. Use the debugger to step into the function and proceed line by line until you find the line of code that is printing to the command window.

You nailed it. Missing semicolon in the function.

Thanks!
