New operational matrices of seventh degree orthonormal bernstein polynomials

الملخص EN

Based on analyzing the properties of Bernstein polynomials, the extended orthonormal Bernstein polynomials, defined on the interval [0, 1] for n=7 is achieved.

Another method for computing operational matrices of derivative and integration and respectively is presented.

Also the result of the proposed method is compared with true answers to show the convergence and advantages of the new method.
