I have a 3D matrix and I`m ttrying to change the zero elements of a certain page (let`s say the third one) to a NaNs. Can someone please help me? That one liner does not work.....
>> data(:,:,3)(data(:,:,3)==0)=NaN;

x(x(:,:,3)==0)=nan;
Start from inside out...above is
isZ=(x(:,:,3)==0);
x(isZ,3)=nan;
w/o the temporary indexing array.
ADDENDUM/ERRATUM: Missing trailing "3" added to original--dpb

Oops. Missed adding the 3rd dimension when made the simplification...since the operation was
isZ=(x(:,:,3)==0)
isZ is 2D logical array -- x(isZ) --> same as x(isZ,1) without explicit 3rd dimension.
As the original shows, you have to address the plane of interest, too...edit'ed the Answer to correct.
Sorry for the typo...trying to clarify just confused.... :(
