Try this:

cmp=colormap(turbo(256));
caxis([-0.5,0.5]);
cmp1=cmp;
cmp1(1:128,:)=flipud(cmp1(129:256,:));
colormap(cmp1);
colorbar

[Dion Akmal]

what is the meaning of turbo?, the error said that turbo is unrecognize function or variable

[G A]

turbo is the name of the predefined colormap, it may be introduced from r2020a

Use instead parula , jet, hsv or any other from the list as:

cmp=colormap(parula(256));

see

doc colormap

Also you can change limits:

caxis([-30,30]);
