Adding Exponent e.g. 10^_10 to Y Axis (normal code for this doesn't work.)

I simply want to change the y-labels on the y axis of my figure from positive to negative.

However, when I try to do this, using this code,

yticklabels = yticklabels % this just saves yticklabels as a variable.

yticklabels_append = append('-',yticklabels) % stick a negative in front of the yticklabels variable and save as yticklabels_append

% at this point, I clear the variable yticklabels. We only need yticklabels_append.

yticklabels(yticklabels_append) % re-assign the yticklabels of the graph to be the one with negatives

Here is the result applied to a figure.

If I run te code above, it indeed puts the minus sign in front of the y tick labels, but watch what happens.

The exponent is deleted...

Does anyone know how to get around this?

Yes, I've already tried this code:

ax.YAxis(2).Exponent=-10; % doesnt work

But it has no effect.

M = 1e10*rand(7,5);
plot(M)
ytickformat('-%g')
