I drew a graph with a variable.

x =[5 2 1 0.5 0.4 0.2 0.1 0.05 0.04 0.02 0.01]

y=[0.020483611 0.140590007 0.551269003 1.46595408 1.896853378 3.587587888 5.525292461 8.535573537 8.227987381 3.137199997 3.142586194]

or example, when x= 3 and 4, which is a value between x=5 and 2,

how can I get the Corresponding y value?

在 MATLAB Online 中打开

Read about interp1.

xi = [2 3 4 5] ; 
yi = interp1(x,y,xi)
