In this paper, solutions of generalized Burger’s–Huxley equation and Burgers equation are proposed through a numerical method. The method is developed by using CAS wavelet in conjunction with Picard technique. Operational matrices for CAS wavelet are derived and constructed. The implementation procedure is provided. Error analysis and convergence of present method is also presented. The results of the CAS wavelet Picard method are compared with results from some well known methods which support the accuracy, efficiency and validity of the CAS wavelet Picard scheme.
