Program name: cat_vector

Language: C

In file: vector_lib.c

Objective: Concatenate two arrays of vectors

Usage: int cat_vector(double ***vector, double **vector_data_ptr, int vector_width,\ int num_vectors_o, int *number_vectors_max, double **vector_i, int num_vectors_i);

Parameters:

• vector - The pointer to the vector array
• vector_data_ptr - Pointer to the actual data - Auxiliary pointer
• vectro_width - The number of elements in each vector (usually around 12)
• num_vectors - Number of vectors in array
• number_vectors_max - Number of elements allocate in memory
• vector_i - Input vector to add to "vector" array
• num_vectors - number of vectors in input vector array

• number of vectors in "vector" array
