I have a range of vectors which are P1,P2,P3 and I would like to write and if statement that if a certain vector is selected a corresponding matrix is selected.

for example if the user puts into the function P1 the corresponding output WP1 will be selected.

What I have tried:

WP1= [2.47 1.93 0;
11.68 2.11 0.01;
18.64 2.2 0.01;
24.87 2.29 0.01;
34.5 2.1 0];


WP2= [1.57 -1.78 0.01;
12.3 -1.5 0;
19.4 -1.3 0;
29.4 -1 0;
35.8 -1.3 0;
40.1 -3.1 0];


WP3= [2.02 1.75 0;
17.3 1.6 0;
27.2 1.1 0;
35.3 1.6 0;
38.2 3.3 0];


P1=[2.47 1.93 0];
P2=[1.57 -1.78 0.01];
P3=[2.02 1.75 0];

P=[P1;P2;P3]
WP=[WP1;WP2;WP3]

if P == P1
WP= WP1;
end
elseif P == Position2
WP= WP2;
elseif P == Position3
WP= WP3;
end


values = input(P1,WP) %% WP needs to be selected automatically based on the choice of P
