I have a quick question:
I was trying to get text on a figure, kindly consider the following:
t = linspace(0,2*pi,50);
y = sin(t);
Following works fine
text(2, 0, '$\theta$', 'interpreter','latex','Position', [0.1 0.8], 'Units', 'normalized' );
But not this
text('$\theta$', 'interpreter','latex','Position', [0.1 0.8], 'Units', 'normalized' );
Why? Can someone please explain.

text Text annotation.
text(X,Y,'string') adds the text in the quotes to location (X,Y)...
Note the X,Y inputs are not documented as optional


Thanks dpb for the reply, I could figure it out.
X and Y were provided with 'Position' property, I was missing 'String' as argument. Just add 'String' to the command.
text('String','$\theta$', 'interpreter','latex','Position', [0.1 0.8], 'Units', 'normalized' );
That works.

Yes, but the first didn't supply all properties via the named parameters in which case the X,Y implied position values must be provided.
While the above form is allowable, what's the point? It's bulkier and more error-prone as you've demonstrated than the shorthand version with only additional parameters that aren't default needing supplied...
