Strange Error Message

Strange Error Message

Strange Error Message

(OP)
I'm running a program in Matlab at the moment and I'm getting the following error:

??? Unable to find subsindex function for class char.

The error is at an input statement of the following syntax:
a=input('\n Text');

Even stranger than that is that the program executed this line perfectly the first time I ran it. The program now stalls at this line regardless of whether a exists or not prior to running the program.

I'm hoping this is something simple, as this is a part of a large program which I don't fancy writing again. Similar code has executed perfectly for me before.

If I clear the variables and the command line history the program will run again, picking a different input statement to stall at each time. Has anyone got any ideas?

RE: Strange Error Message

(OP)
I found out what caused the error anyway. The program defined a variable named input in the line before the input statement that caused the problem.
