How to call element from vector out of t = @(theta) x*cos(thet​a)-y*sin(t​heta);

x = linspace(1,10,10);
y=x;
t = @(theta) x*cos(theta)-y*sin(theta);

t(0.1) will give me vector. How to get element 5 ?

My approach:

tv = t(0.1);
t5 = tv(5)          % Element 5

Thanks. I was hoping theres some trick without the need of allocating it again t(0.1)(5) .

My pleasure.

Unfortunately, not.

The only way around it is to include ‘x’ and ‘y’ as arguments, then reference the 5th element of each:

txy = @(theta,x,y) x*cos(theta)-y*sin(theta);
t5 = txy(0.1,x(5),y(5))

----------

This strange construction actually works (it creates a cell array, and then references the 5th element and assigns the correct value to t5), but throws an annoying error and halts execution of the script:

t5 = {t(0.1)}(5)
