Dear All,

Just a simple question, I need to find x_15, where x_15 is x at y=15. Please imagine x and y as below,

x y 0.1 20 0.05 15 0.2 85

Thank you!

Hi.

x=[0.1; 0.05; 0.2]; y=[20; 15; 85]; x(y==15)

See this works:

s4_01nov=rand([5357 1]); el1nov=randi(20,[5357 1]); plot(s4_01nov(el1nov==15)./sin(el1nov(el1nov==15)))

but with for example 30, because el1nov doesn't have 30 nothing happened. With nnz(el1nov==15) you can check how many 15 in the el1nov vector:

nnz(el1nov==15) nnz(el1nov==30) plot(s4_01nov(el1nov==30)./sin(el1nov(el1nov==30)))
