Pausing Execution

David Doria — Thu, 05 Jun 2008 19:12:01 -0400

When you run a big program, sometimes it would be nice to be
able to say "stop for a second so I can look at something",
but then continue. The only way I know how to stop it at
all is with ctrl-c. Is there something similar to an
"interrupt" where in your program you can say "pause if a
key is pressed" without polling every time through a loop?

This seems like a very common thing to want to do, at least
among my coworkers.

Any suggestions would be great.

Thanks,
Dave

No there isn't, not in Matlab itself. See though this
recent thread,

has anyone used that dbloop function? The comment on the
file exchange says it slows the code down significantly - is
this true?

Also, how do you set a breakpoint programmatically?
