how can i get the exponential from a matrix  cant find the function. how can i build it



You are referring to
this function? We do not support it out of the box yet, but we certainly want to have it in the future as it has a few very useful use cases.



Hello cdrnet  yes this is the Function i want to use...
Now i have build it for my owen
Thank you for replay



Hello,
I'm working on the same. Fitting and exponential.
I still cannot found any solution (for free). Did you make any progress?

Hello Jaroslav
I have found an easy way
Algorithmus:
E = expm(A)
Situation: A
∈ R4×4
tol := 0.001
Identity Matrix E, I
∈ R4×4
k = 1
repeat
I := A
∗ I/k
E := E + I
k := k + 1
until E < tol
Return: E
