Here the values of s1 can be 0,1/2,1,3/2

But in my for loop the values of s1 is integer, how to give the fractional values to s1

clc; clear all; close all;
M=3
for m1 =0:M
    for s1=0:m1/2
        X=2^(s1)
    end
end
X

Hi, you just need to add in a step size like this:

for i = 1:0.5:3 % Here, step size is 0.5
    i
end
i = 1
i = 1.5000
i = 2
i = 2.5000
i = 3

You wouldn't need to create two loops if you're using the step size:

clc; clear all; close all;
M=3;
for m1 =0:0.5:M
    X = 2^(m1)
end
X = 1
X = 1.4142
X = 2
X = 2.8284
X = 4
X = 5.6569
X = 8
X
X = 8

You should spend some time understanding the fundamentals of MATLAB
