C-like operations

I wonder wether Matlab could include a form of arithmetic operations common in C, namely x+=y, x*=y, x/=y etc.
In the piece of code
ctrl = somevar <= someother;
x(ctrl) = -x(ctrl);
indexing takes place twice, while x(ctrl)*= -1; could possibly save some time, unless the optimization of the Matlab interpreter makes this idea obsolete.
Anybody has an answer? Thanks

Hello Enrico,
Such operations are not supported by MATLAB. You can go through the post 11 ( Steven Lord's answer ) I have attached below, which says that since MATLAB is array based, such operator would be ambiguous and unintuitive.
Hope it helps :)

Enrico Onofri's "Answer" moved here:
I believe that a scalar operation like v= v*a should be simply v*=a at no risk (v matrix, a scalar). Also V(indices)*=a ; would be better than V(indices)=V(indices)*a. Where is the danger? I’m not convinced! Thanks anyway.
