Summation with independent variables as different sized arrays in matlab
0
I am new to matlab and am learning it on my own. I am trying to solve and graph the following summation in matlab
t = [0:.05:60]
y = [0:1:100]
u = symsum(sin(((n*pi)/h)*y)*(-((2/(n*pi*rho))*(cos(n*pi)-1))*((P1/((mu*(pi^2)*(n^2))/(h^2)))*(1-exp(-((mu*(pi^2)*(n^2))/(h^2))*t))+P2*((((mu*(pi^2)*(n^2))/(h^2))*(cos(omega*t)-exp(-((mu*(pi^2)*(n^2))/(h^2))*t))+omega*sin(omega*t))/(((mu*(pi^2)*(n^2))/(h^2)))^2+(omega^2)))),n,1,10)
All of the other variables in the sum are numbers.
However, I keep getting the following errors:
Error using symengine
Dimensions do not match.
Error in sym/privBinaryOp (line 1002)
Csym = mupadmex(op,args{1}.s, args{2}.s, varargin{:});
Error in * (line 315)
X = privBinaryOp(A, B, 'symobj::mtimes');
How do I correct my code to run correctly?

tandyare row vectors of different sizes. In MATLAB,*is matrix multiplication, and.*is element-wise multiplication, but neither seems applicable.
