How to create a new Matrix for acceleration?

[vlehner]

Hello,

I have solved a DGL with Rkadapt-Routine (Runge-Kutta-Verfahren, adaptiv) , whitch generated following arrays:

Now i want to build the acceleration-Matrix by dividing vx over t.

So i have to divide each Element and write them into a new Matrix for the acceleration.

I think we have to write a little program for it and that's my problem.

Can please somebody help me to program it?

Thank you for your efforts.

best regards, Volker

Actually, you want to take the difference in the velocities and the times, and divide those:  acceleration is the slope of velocity

first element Acc[0 will be null

[-MFra- · Accepted solution]

Hi Volker,

I have adapted the worksheet to PRIME 4 (with carriage return for the sum and subtraction, and constant font size) as well as having traced the graphic of the acceleration calculated in two different approximations.

Thank you all for your efforts.

That works perfectly!

I have to do some more with arrays and Matrices.
