If I havea 1x15 matrix, and I want to call elements 7,8,9 and 14, how would I go about putting it in the second line of code within parenthesis?
Soln = [AB; AI; BI; BC; CH; CI; CD; DE; EH; EG; EF; FG; DH; HI; GH]
Soln(???)

See Ch 5 of MATLAB Onramp (indexing into and modifying arrays)

I know to use Soln(7:9) for the first three, but how can I incorporate the 14?

Ran in:
That is covered in Ch 5, but enclose all the numbers in square brackets.
A=1:10;
b=A([3:5 8])
b = 1×4
3 4 5 8
