| Abstract: | Some special problems are solved with the functions provided by MATLAB. Double integral defined on nonsquare regions is numerically evaluated with the function QUAD used for definite integral and DBLQUAD for double integral on square regions. Tridiagonal block matrix is expediently built with the DIAG and KRON. Symbolic matrix of arbitrary order is built by programming. |
