Can someone please help on how to write the following function please.
I have 3 3x3 Rotation Matrices.
2 of which are Identity Matrices.
R1 = eye(3,3)
R2 = eye(3,3)
R3(3,3) = zeros
R3(1,1) = cos(xHat_BM(3,1))
R3(1,2) = sin(xHat_BM(3,1))
R3(2,1) = -sin(xHat_BM(3,1))
R3(2,2) = cos(xHat_BM(3,1))
R3(3,3) = 1
xHat_BM will be updated for each iteration (separate section of code)
How do I create a function so that said function grabs the xHat_BM value from the script, uses it for the rotation angle calculations (R3 elements in the function), then outputs the updated R3 matrix (M_BM)back into the script for the next iteration?
Thanks in advance.
