We have a column matrix $P_i$ defined as follows $P_i= {\begin{pmatrix} a_i \\ b_i \\ c_i \end{pmatrix}}_{3\times 1}\tag 1 $.
Given Data
- All $a_i,b_i,c_i$ are constants
- It is given that $i$ can only take four values such that $i=0,1,2,3$. Means we are considering $P_0,P_1,P_2,P_3$ only.$P_i$s must be unique
- s is not matrix(mentioned below). $s\in[0,3]$. Means is a parameter which can take values from $0$ to $3$
Question
Can we make a function ${Q(s)}_{3\times1}=f(s,P_1,P_2,P_3,P_4),\tag 2$
such that $\frac{\mathrm{d} Q(s) }{\mathrm{d} s} $ is a constant column matrix and satisfying the following condition
- $Q(0)=P_0 ,Q(1)=P_1 ,Q(2)=P_2 ,Q(3)=P_3 ,$
NB:: There are no other constraints on $Q(s)$ . All constraints are already mentioned in question and data section above. Thanks for reading this question
