I would remove the 'matrix' portions of the function names, since this
information is already contained in the module name. E.g. after importing
LinearAlgebra.Matrix as Matrix, Matrix.matrix look strange, but
Matrix.fromList says everything.
I suggest
matrix -> fromList
matrixElements -> toList
displayMatrix -> display
readMatrix -> fromFile :: FilePath -> IO Matrix
writeMatrix -> toFile :: FilePath -> Matrix -> IO ()
blockMatrix -> fromBlocks or fromMatrices
subMatrix -> clip or cut or take
matrixScale -> scale
matrixOffset -> offset
matrixAdd -> add
matrixSub -> sub
matrixMul -> mul (element-wise multiplication?
then better zipMul or elementwiseMul, elMul what know I :-)
matrixDiv -> div
matrixSigns -> signs
matrixAbs -> abs
matrix_x_matrix ... hm difficult
matrix_x_vector
vector_x_matrix
msin :: Matrix -> Matrix
mcos :: Matrix -> Matrix
mtan :: Matrix -> Matrix
masin :: Matrix -> Matrix
macos :: Matrix -> Matrix
matan :: Matrix -> Matrix
matan2 :: Matrix -> Matrix -> Matrix
msinh :: Matrix -> Matrix
mcosh :: Matrix -> Matrix
mtanh :: Matrix -> Matrix
masinh :: Matrix -> Matrix
macosh :: Matrix -> Matrix
matanh :: Matrix -> Matrix
mexp :: Matrix -> Matrix
mlog :: Matrix -> Matrix
If there are no efficiency concerns, I would drop element-wise operations
and prefer a matrix-map and a matrix-zipWith. If these operations shall
remain I would somehow point to their element-wise operation in the name.
