Operations with matrices
Extracting rows, columns, elements: col, el, row, submatrix, vminor, minor
col("1:matrix", "2:number") - Returns the specified column "2:number" of the matrix/vector "1:matrix".
el"1:vector", "2:number") - Returns the specified column "2:number" of the vector "1:vector".
row("1:matrix", "2:number") - Returns the specified row "2:number" of the matrix/vector "1:matrix".
submatrix("1:matrix", "2:argument", "3:argument", "4:argument", "5:argument") - Returns the submatrix consisting of elements in rows "2:argument" through "3:argument" and columns "4:argument" through "5:argument"
vminor("1:matrix", "2:number", "3:number") - Returns submatrix with the specified row ("2:number") and column ("3:number") removed from the given matrix ("1:matrix").
minor("1:matrix", "2:number", "3:number") - Minor of matrix.
