I have the followling code which has values calculated that are inputs of two matrices A and B. The inputs are values that are calculated in a for loop of i=1:365 corresponding to 1 degree to 360 degrees. I need each value computed by dividing the matrices at each degree/iteration. Everything else works besides the matrix part. I am not including the portions of my code that calculate the inputs but know they are within the for loop
for i=1:360
%All my stuff getting the inputs of the matrices
A(i)=[1 0 1 0 0 0 0 0
0 1 0 1 0 0 0 0
-R12x(i) R12y(i) -R32y(i) R32x(i) 0 0 0 1
0 0 -1 0 1 0 0 0
0 0 0 -1 0 1 0 0
0 0 R23y(i) -R23x(i) -R43y(i) R43x(i) 0 0
0 0 0 0 -1 0 0 0
0 0 0 0 0 -1 1 0]
B(i)=[m2.*A2x(i)
m2.*A2y(i)
I2*a2
m3*A3x(i)
m3*A3y(i)
I3*a3(i)
m4*A4x(i)-F4x(i)
0];
F(i)=A(i).\B(i)
end

i get the error -"Unable to perform assignment because the left and right sides have a different number of elements"

B(i)=[m2.*A2x(i);
m2.*A2y(i);
I2*a2;
m3*A3x(i);
m3*A3y(i);
I3*a3(i);
m4*A4x(i)-F4x(i);
0];%need 8x1 matrix
