In the above code, we use the library function, i.e., malloc().As we know, that malloc() function allocates the memory; if malloc() function is not able to allocate the memory, then it returns the NULL pointer. It is similar to final variables. Armadillo uses BLAS for matrix multiplication, meaning the speed is dependent on the implementation of BLAS. data_type is the pointer's base type of C's variable types and indicates the type of the variable that the pointer points to. Given two sparse matrices (Sparse Matrix and its representations | Set 1 (Using Arrays and Linked Lists)), perform operations such as add, multiply or transpose of the matrices in their sparse form itself.The result should consist of three sparse matrices, one obtained by adding the two input matrices, one by multiplying the two matrices and one obtained by transpose of the first matrix. Since the multiplication of two nonsingular matrices creates another nonsingular matrix, the entire transformation matrix is also invertible. CUDA C++ extends C++ by allowing the programmer to define C++ functions, called kernels, that, when called, are executed N times in parallel by N different CUDA threads, as opposed to only once like regular C++ functions..
