Click For Summary
The discussion focuses on coding a Vandermonde matrix inverse in Java for a third-degree polynomial. The user successfully creates the Vandermonde matrix and its transpose but struggles with coding the inverse. They seek assistance on how to implement the matrix inverse in their program. The coefficients a, b, c, and d represent the polynomial f(x) = ax^3 + bx^2 + cx + d. The conversation emphasizes the need for coding guidance specifically in Java.

I have to right a computer program that uses data inputted by the user, creates a vandermonde matrix (3rd degree) and than computes the values of a, b, c and d. I can create the vandermonde matrix, find the transpose and than multiply. However, I can't seem to figure out who to find the inverse. I do know how to find the inverse, but i can't seem to code it. I was just wondering how I would code it to right the matrix inverse. Any help would be appreciated. (is this in the right section?)

What language are you writing this program in?
 
And what are a,b,c, and d?
 
a, b, c, d and coefficients of the polynomial, that is
f(x) = ax^3 + bx^2 + cx + d

and in either java or c++ (preferably java since I'm more fimiliar with it)

Thread 'How to define a vector field?'

Hello! In one book I saw that function ##V## of 3 variables ##V_x, V_y, V_z## (vector field in 3D) can be decomposed in a Taylor series without higher-order terms (partial derivative of second power and higher) at point ##(0,0,0)## such way: I think so: higher-order terms can be neglected because partial derivative of second power and higher are equal to 0. Is this true? And how to define vector field correctly for this case? (In the book I found nothing and my attempt was wrong...
