To multiply two matrices, the
column dimension of
matrixA must equal the row
dimension of matrixB .

Multiplies matrixA and matrixB; returns a square matrix of the
products
Returns a matrix that is the product of a real or complex number
times each element in a real or complex matrix
Returns a vector that is the product of each vector element times each
matrix element; the matrix column dimension and vector dimension
must be equal
(negation) Changes the sign of each element in matrix
Returns the inverse of squareMatrix (not the inverse of each element)
Squares a square matrix
Raises a squareMatrix to the designated power
Returns the square matrix exponential of a real squareMatrix
Returns the square matrix sine of a real squareMatrix
Returns the square matrix cosine of a real squareMatrix
Returns 1 if every corresponding element comparison is true; returns
if any is false
0
Returns 1 if at least one corresponding element comparison is false
) Rounds each matrix element to 12 digits or to specified #of Decimals
Returns the integer part of each element of a real or complex matrix
Returns the fractional part of each element of a real or complex
matrix
Returns the greatest integer of each element of a real or complex
matrix
