Abstract
This presents a refined approach for computing integral and product operators by using the rich properties of Legendre wavelet.The most advantages of this refined calculations are that the operational matrices are lower dimensions, coarse and its elements are the same on each subinterval, respectively. The operational matrices are applied to solving the minimum of integral function from heat conduction problem. The essence of this technique is to transform the optimization of integral function into that of Legendre wavelet coefficients, which is solved by Lagrange-multiplier method. The good results demonstrate that this technique is valid and applicable.

Keywords
Legendre wavelet; operational matrix of integration; operational matrix of product; refined calculation; minimum of integral function.
