Return interpolated matrix for given input
This one-dimensional case assumes a matrix M is defined at a discrete number of values of an independent variable
x = [ x1 x2 x3 ... xi xi+1 ... xn ].
Then for xi < x < xi+1, the block output is given by
where the interpolation fraction is defined as
The matrix to be interpolated should be three dimensional, the first two dimensions corresponding to the matrix at each value of x. For example, if you have three matrices A, B, and C defined at x = 0, x = 0.5, and x = 1.0, then the input matrix is given by
matrix(:,:,1) = A;
matrix(:,:,2) = B;
matrix(:,:,3) = C;
|Contains the interpolation index i.|
|Contains the interpolation fraction λ.|
|Contains the interpolated matrix.|
