The operator clear_all_matrices frees the memory of all matrices that were created by create_matrix or another matrix operator. After calling clear_all_matrices, no matrix can be used any longer.
clear_all_matrices exists solely for the purpose of implementing the “reset program” functionality in HDevelop. clear_all_matrices must not be used in any application.
clear_all_matrices always returns the value 2 (H_MSG_TRUE).
