vSgemul(_:_:_:_:_:_:_:_:)

Declaration

func vSgemul(_ l: Int32, _ m: Int32, _ n: Int32, _ a: UnsafePointer<vFloat>, _ forma: CChar, _ b: UnsafePointer<vFloat>, _ formb: CChar, _ matrix: UnsafeMutablePointer<vFloat>)

Parameters

• l:

  Number of rows in matrix matrix; must be a multiple of 4.

• m:

  If forma = ‘N’, m is the number of columns in matrix a ; if forma = ‘T’, m is the number of rows in matrix a. Also, if formb = ‘N’, m is the number of rows in matrix b; if formb = ‘T’, m is the number of columns in matrix b. m must be a multiple of 4.

• n:

  Number of columns in the matrix matrix; must be a multiple of 4.

• a:

  A matrix with elements of type float. If forma = ‘N’, the matrix itself is used in the calculation and it has l rows and m columns. If forma = ‘T’, the transpose is used and a has m rows and l columns. Thus the matrix used in the calculation is l by m.

• forma:

  Selector with a value of ‘N’ or ‘T’.

• b:

  A matrix with elements of type float. If formb = ‘N’, the matrix itself is used in the calculation and it has m rows and n columns. If formb = ‘T’, the transpose is used and b has n rows and m columns. Thus the matrix used in the calculation is m by n.

• formb:

  Selector with a value of ‘N’ or ‘T’.

• matrix:

  Destination matrix with l rows and n columns.

Discussion

Matrix a (or its transpose) is multiplied by matrix b (or its transpose); the result is stored in matrix matrix.
