 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.
