find missing points on a graph

hi every body. I have written this code

a=[1,3,4,6,7,9]

b=[2,12,24,32,41,49]

plot(a,b,'r-')

hold on

plot(a,b,'ko','LineWidth',2,'DisplayName','KnownCorrespondence')

i want to find 3 points on the above graph which i have the a values of them only

a_missing=[2,5,8]

how can i find the b_missing values correspond to a_value on the graph?

a=[1,3,4,6,7,9]
b=[2,12,24,32,41,49]
plot(a,b,'r-')
hold on
plot(a,b,'ko','LineWidth',2,'DisplayName','KnownCorrespondence')
% get missing 
x = min(a):max(a) ; 
missing = setdiff(x,a)

sorry sir. i dont want to find the missing data of a, i know them that are 2,5,8.

i want the y values of them to find the points in order to be on the graph.

i have the plot and the x values on them, i want to find the y values

Simple use interp1. Read about it.
