Reduction method

Updated 22 Jun 2007

In this Matlab application was perused Jean Le Rand D'Alambert's** Reduction Method for two degree of linear differential equations and several analytical examples are compared with matlab solution applications.

**Jean d'Alembert was a a French mathematician who was a pioneer in the study of differential equations and their use of in physics. He studied the equilibrium and motion of fluids (1717-1783).

Example reduction method;

[Analytical problem]
y'' - 4xy' + [4x^2-2]y = 0 and equation's is know one solution
y1(x)=exp(x^2)

[Matlab application]
Dalambert(1,-4*x,(4*x^2-2),exp(x^2),1)

mis spell

Note that even the title of the submission has two misspells: "Jean Le ROnd d'AlEmbert"!

'Lineer Differantial'?'Symoblic'? I don't expect much from a contributor who doesn't bother to use spell-check. Despite evident effort, the HTML report is shoddy and difficult to understand. Is all the FPRINTFed output necessary? What toolboxes are needed? (The code invokes SYMS and MAPLE, for example).
