MATLAB: Solving Complex Matrix Operations

I have tried everything!

Best Answer

You can do this in a for loop or using arrayfun

% your A vector
A = rand(1,1001);  % dummy vector
% calculation of the matrix B
B = arrayfun(@(a)[cos(-a) sin(-a) 0; -sin(-a) cos(-a) 0; 0 0 1],A,'UniformOutput',false);

Than you can access each matrix using the {} indexing, e.g. the first matrix is

B{1}

etc

Use element-wise operations (the ‘dot operator’):

x=e*cos(theta)./sqrt(4/3+4/3*cos(theta).*sin(theta));
y=e*sin(theta)./sqrt(4/3+4/3*cos(theta).*sin(theta));

That worked when I ran it.

EDIT —

You can plot them all at the same time (without loops) by using matrix operations as well as element-wise (array) operations:

theta=0:0.1:(2*pi);
e=[0.1; 0.2; 0.3; 0.4];
x=e*cos(theta)./sqrt(4/3+4/3*cos(theta).*sin(theta));
y=e*sin(theta)./sqrt(4/3+4/3*cos(theta).*sin(theta));
plot(x.',y.')

Set a dot (.) before each ^2-operation.
