PEEI program calculate a apart, numerical and come near solution from a model diferensial the analytical public (i.e. a system of equation diferensial partial).
Are exposed bases mathematical from a computer program to numerically to break the model diferensial the analytical, i.e. system of equation diferensial partial. Elaborated by analytical properties from two famous model to come near function from a variable (insert polynomial and spline the cubic) and new boundary upper bounds for mistake of the second obtained. Introduced the important aspect from a curve in Euclidean space multidimensional, to the purpose of to depicting directional derivative from a function and to obtain a upper bound for absolute maximum value from a limited derivative in a curve. Is shown, for a point where is intersect more curves, expression from a partial derivative as combination liniar from directional derivative, and of it deduced by estimate of optimum when values from this to closing. Formulated by expression from a model diferensial the analytical public, highlighting is in detail its argument, don't identify the principal barrier to knowledge from a its correct solution in knowing partial derivatives, circumstantiate context of information contingently available, and showing how is it countable a its numerical solution solving an inherent system of not equation diferensial. Is exposed in detail the algorithm express a derivative of this system as combination liniar from its variable. Finally it introduced, depict its usage characteristic and important action, PEEI the program realized, on the basis of previous treatment, calculate the numerical solution of model diferential the analytical
