aspcore.matrices.blockmat2param

aspcore.matrices.blockmat2param(R, num_blocks, block_len)

Converts from a standard block matrix to a parametrized form

Parameters:

• R (ndarray of shape (num_mic * ir_len, num_mic * ir_len)) – The input block matrix in standard form. Assumes for now that the matrix and the blocks are square.

• num_blocks (int) – The number of blocks in each dimension.

• block_len (int) – The length of each block.

Returns:

param_mat – The output block matrix in parametrized form.

Return type:

ndarray of shape (num_mic, num_mic, ir_len, ir_len)

Notes

The parametrized form is a block matrix where each (identically sized) block is accessed as R[i,j,:,:]. The standard form is a matrix, where the same data is accessed as R[i*len1:(i+1)*len1, j*len2:(j+1)*len2].
