fsine=50e6:0.4e9:3e9;
Vp=0:0.5:3;
I need to form a matrix such that columns correspons to different Vp for a single fsine.
the first column should be for fsine=50e6 for all values for Vp and second column should be fsine=50e6+0.1e9 for all values in Vp
The final vector should be have 7 rows and 8 columns.

Hi Yogesh
The following code might help you:
fsine=50e6:0.4e9:3e9
fsine = 1x8
1.0e+09 * 0.0500 0.4500 0.8500 1.2500 1.6500 2.0500 2.4500 2.8500

Vp=0:0.5:3
Vp = 1x7
0 0.5000 1.0000 1.5000 2.0000 2.5000 3.0000

M=zeros(7,8);
for idx1=1:7
for idx2=1:8
M(idx1,idx2)=sin(fsine(idx2)*Vp(idx1));
end
end
M
M = 7x8
