Returns the value(not a pointer) of space the `data_ref` pointer pointed to. This function is mainly for debugging. * __Matrix/Element\_type, boolean Matrix.\_\_index\_\_(Matrix self, int index)__ If the matrix has more than one row, will return the row at `index` as a __Matrix__ . Otherwise it will return the value at `index`. -* __void Matrix.\_\_newindex\_\_(Matrix self, int index, Element_type value)__ +* __void Matrix.\_\_newindex\_\_(Matrix self, int index, Element_type value)__ Set the element at `index` to be `value`. --- +* __Matrix Matrix.create(Matrix a)__ +Return a new __Matrix__ of `a`'s size(of the same number of rows and columns). +* __Matrix Matrix.colsum(Matrix self)__ +Return a new __Matrix__ of size (1,`self.ncol`), which stores the sum of all columns of __Matrix__ `self`. +* __Matrix Matrix.rowsum(Matrix self)__ +Return a new __Matrix__ of size (`self.nrow`,1), which stores the sum of all rows of __Matrix__ `self`. +* __Matrix Matrix.rowmax(Matrix self)__ +Return a new __Matrix__ of size (`self.nrow`,1), which stores the max value of all rows of __Matrix__ `self`. +* __Matrix Matrix.trans(Matrix self)__ +Return a new __Matrix__ of size (`self.ncol`,`self.nrow`), which stores the transpose of __Matrix__ `self`. +* __void Matrix.copy_fromh(Matrix self, MMatrix a)__ +Copy the content of a __MMatrix__ `a` to __Matrix__ `self`, they should be of the same size. +* __void Matrix.copy_fromd(Matrix self, CuMatrix a)__ +Copy the content of a __CuMatrix__ `a` to __Matrix__ `self`, they should be of the same size. +* __void Matrix.copy_toh(Matrix self, MMatrix a)__ +Copy the content of the __Matrix__ `self` to a __MMatrix__ `a`. +* __void Matrix.copy_tod(Matrix self, CuMatrix a)__ +Copy the content of the __Matrix__ `self` to a __CuMatrix__ `a`. +* __void Matrix.add(Matrix self, Matrix ma, Matrix mb, Element_type alpha, Element_type beta)__ +It sets the content of __Matrix__ `self` to be `alpha * ma + beta * mb`.__Matrix__ `ma,mb,self` should be of the same size. +* __void Matrix.mul(Matrix self, Matrix ma, Matrix mb, Element_type alpha, Element_type beta, [string ta, string tb])__ +It sets the content of __Matrix__ `self` to be `beta * self + alpha * ma * mb`. `ta` and `tb` is optional, if `ta` is 'T', then `ma` will be transposed, also if `tb` is 'T', `mb` will be transposed. +* __void Matrix.add_row(Matrix self, Matrix va, Element_type beta)__ +It sets the content of __Matrix__ `self`(which should be row vector) to be `self + beta * va`. +* __void Matrix.fill(Matrix self, Element_type value)__ +Fill the content of __Matrix__ to be `value`.
