# MATLAB: Plotting the different solution via fzero solver against a range of one of the variable

2d plot2dplotplot

I am bit new to the matlab; I am having trouble with this, I got different values of phi0 at different Nt using fzero solver; called phi0value. I want to plot Nt v/s phi0value? I used plot (Nt, phi0) for this, it is not working. I dont know how to plot a range of output against a range of variable? Please guide me through this.This will be a great help!! Thank You.
