Matlab Circuit Analyse coding

I am undergraduate student from Turkey, looking for advices that you may suggest me.

1.

Vs=150e-3;

L=750e-6;

for t=0:1:100;

i=(Vs*t)/L

plot(i,t)

xlabel('Current for t values ')

ylabel('Time values ')

end

2.

a=input('input t value for a specific time(milisecond format) ')

t=a*10^-3

if t<=0

L=50e-3;

vL=0;

C=0

i=100e-3

elseif t>=0 && t<=100e-3

for x=[0: 1e-3: 10e-3]

t=[0: 1e-3: 10e-3];

C=100e-3;

i=((-exp(-100*t))/50)+C;

vL=2*exp(-100*t);

plot(vL,i,'g')

end

else

for x=[100e-3: 1e-3:1]

t=[100e-3:1e-3:1];

C=1;

vL=-2*exp(-100*(t-0.1));

i=((exp(-100*(t-0.1)))/50)+C;

plot(vL,i,'c')

end

end

My codes are broken and can not satify the sketches that I am looking for.

Hello !

Current expression is not simply votage*t/L, it is actually intigration of voltage/L with respect to time. Derive proper current equations in time domain and apply the same for loop, you will see the results you want to see.
