Interpolate Matrix(x,y)
Matrix Interpolation.
Description
The Interpolate Matrix(xy) block interpolates an array of matrices. The array to be interpolated must be four-dimensional: the first two dimensions correspond to the rows and columns of the matrices, the third and fourth dimensions correspond to the matrix indices in the array. For example, if it is necessary to specify four matrices of size 2 by 2 , , and for ( ), ( ), ( ) and ( ) respectively, then the value of the Matrix to interpolate parameter is set as [A; ; ; ; B; ; ; ; ; ; C; ; ; ; D]. The resulting array has size 2 by 2 by 2 by 2 by 2 by 2.
The interpolated matrix is calculated by the formula:
where - -th array matrix, - interpolation parameters.
Interpolation parameters и are equal to
Ports
Input
xk - the first index of the matrix
scalar

scalar
First interpolation parameter . The parameter takes a value from 0 to 1.
Data types: Float64.
yk - second index of matrix
scalar
The second index of the matrix in the array. Indexing starts from zero.
