Hola Hola.. was wondering how to make it so, that I can know exactly the value of y for a given x when x and y are arrays. I've seen many options online but I just get an empty []. Please help. I have the graph below and want to extract the y values of all three lines (I've given only info on one of the three)along different x values, for example x=0.5, x=0.55, x=0.6, x=0.65. and y are
x=linspace(0.46,0.7,281);
y=wdth_8mm;(see attached file);

Let (x,y) be data you have. And you want to find yi for given xi. For this you have to do interpolation. Read about interp1.
yi = interp1(x,y,xi)
