MATLAB Troubleshooting Syntax Errors in MATLAB 'if' Blocks

[hoffmann]

What is wrong with this statement in an 'if' block?

if ((scalar1 == 0) || (scalar2 == 0) || (scalar3) == 0 || (scalar4 == 0))

I basically want to say: if any of the four scalars are individually equal to zero, then execute the subsequent statements.

I receive the following error in the command line:
Operands to the || and && operators must be convertible to logical scalar values.

Any suggestions?

First, thanks for an exceedingly rare Matlab question that cannot be answered "rtfm"

It looks to me like the problem is the parentheses around scalar3

(scalar3)==0

instead of

(scalar3==0)

You know, I thought I had scoured the whole line for a possible mistake. I swore that there wasn't one...but thanks for pointing that out. Wow, I feel like a fool, but at least I can laugh about it now.

Eyes like a hawk.

I spent a good ten minutes looking at the question while trying to figure out why the code wouldn't work. Then I noticed the brackets!
