## Detailed Description

For each of the following built-in matrix functions, there is both a single-precision floating point version, where all arguments and return values are single precision, and a double-precision floating version, where all arguments and return values are double precision.

Only the single-precision floating point version is shown.

GLM_FUNC_DECL matType<T, P> glm::matrixCompMult | ( | matType< T, P > const & | x,
|  | matType< T, P > const & | y
| ) |  |

Multiply matrix x by matrix y component-wise, i.e., result[i][j] is the scalar product of x[i][j] and y[i][j].

Template Parameters

  matType | Floating-point matrix types.

GLM_FUNC_DECL detail::outerProduct_trait<T, P, vecTypeA, vecTypeB>::type glm::outerProduct | ( | vecTypeA< T, P > const & | c,
|  | vecTypeB< T, P > const & | r
| ) |  |

Treats the first parameter c as a column vector and the second parameter r as a row vector and does a linear algebraic matrix multiply c * r.

Template Parameters

  matType | Floating-point matrix types.
