Toolbox

This repositories offers a toolbox across platforms.

How to use

• MatlabFuncHelper: this class simulate all Matlab functions in python (batch is supported).
  • checkers
    • isvector()
    • ismatrix()
  • generators
    • zeros()
    • ones()
    • eye()
    • seq(): generate a sequence
    • rand():
    • randn():
    • dftmtx(): generate the discrete transform matrix
  • transformers
    • squeeze(): remove redundant dimension except for the batch_size
    • reshape():
    • repmat1(): repeat the matrix in the given dimension (the batch dim is repeated as 1)
    • repmatN(): repeat the matrix in the given dimension (the batch dim is repeated as batch_size)
    • diag(): generate a matrix based on its diag or get a diagonal matrix from its vector
      @mat: a vector as [(batch_size), n, 1] or [(batch_size), 1, n]; if n == 1, it will be taken as [(batch_size), n, 1]. Or a square matrix [(batch_size), n, n]
    • circshift(): circular shift (1st index except for the batch size)
      @mat: [(batch_size), dim1, dim2, ...]
      @step: a scalar or an 1D array (only for batch)
  • Maths
    • max(): return the maximum value of a matrix or the maximu value of two matrices (for complex value, we compare the magnitude)
    • kron(): Kronecker produc
