I want to draw graph for those two equations with MATLAB MAT

I want to draw graph for those two equations with MATLAB. MATLAB code plz.

There are some conditions.

(1) x axis for v_id, y axis for i_d1 and i_d2 total two graphs.

(2) k_n prime = 100A/V^2

vid=-100:1:100;

kn=100;

x=1;

%w/l=X

I=100.*10.^-6;

Id1=(I/2)+sqrt(kn.*x.*I).*(vid/2).*sqrt(1-((vid/2).^2./((I/kn).*x)));

Id2=(I/2)-sqrt(kn.*x.*I).*(vid/2).*sqrt(1-((vid/2).^2./((I/kn).*x)));

plot(vid,Id1,vid,Id2)

vid=-100:1:100;

kn=100;

x=2;

%w/l=X

I=50.*10.^-6;

Id1=(I/2)+sqrt(kn.*x.*I).*(vid/2).*sqrt(1-((vid/2).^2./((I/kn).*x)));

Id2=(I/2)-sqrt(kn.*x.*I).*(vid/2).*sqrt(1-((vid/2).^2./((I/kn).*x)));

plot(vid,Id1,vid,Id2)

vid=-100:1:100;

kn=100;

x=10;

%w/l=X

I=200.*10.^-6;

Id1=(I/2)+sqrt(kn.*x.*I).*(vid/2).*sqrt(1-((vid/2).^2./((I/kn).*x)));

Id2=(I/2)-sqrt(kn.*x.*I).*(vid/2).*sqrt(1-((vid/2).^2./((I/kn).*x)));

plot(vid,Id1,vid,Id2)
