Most probably the error is not related to this line of code. Please, post more details (e.g., the piece of code and the whole matlab error message, including the line at which the error is found).

I.e., several lines above and below the offending line.

The ~ operator was not implemented until R2009b. You can replace that code with

[UnUsEdVaRiAbLe_To_IgNoRe, ant_est] = max(abs(z));
clear UnUsEdVaRiAbLe_To_IgNoRe

Don't clear the variable if time is more of an issue than memory. clear instructions take a lot of time, relatively.

I would be unlikely to clear the junk variable myself, unless I was short on memory. The "clear" I showed is the logical equivalent, not the practical equivalent.
