Hi All,
Good day!
I'm very-very new to MATLAB, and had a very limited exposure to other programming languages (learn an introduction course in FORTRAN but then it was more then 25 years ago).
I need to calculate a transient characteristic of simple dynamic system. Its seems like a very simple and straight forward loop coding but i couldn't figure out from standard MATLAB manual in the time that is available to me.
The problem as follow; I have some constants and initial conditions.
Use the constants in the formulas and then simple calculate the rest. The output of the previous formula becomes the input of the next.
And i'm going to recalculate those with fixed time increment, and able to tell the program at what time to stop.
Finally, i want it to be plotted, for example in this case the cumulative values of DVTn vs Time.
So, please help me on how to do this in MATLAB.
Any form of helps would be very much appreciated.
Thanks !!!

VCG = 15;

CR=0.65;
AFN = 1.1*10^(-6);

AINJ = (20*10^(-7))^2;
IPD=9*10^(-7);
CFG=(3.9*8.85*10^(-14)*AINJ)/IPD;
VFG0 =CR*VCG;
EOX0 = VFG0/TOX;
JFN0 = AFN*EOX0^2*exp(-BFN/EOX0);
DQFG0 = JFN0*AINJ*1*10^(-9);
DVT0 = DQFG0/CFG;
DVT0
'after 1 ns'
VFG1 =CR*(VCG-DVT0);
EOX1 = VFG1/TOX;
JFN1 = AFN*EOX1^2*exp(-BFN/EOX1);
DQFG1 =JFN1*AINJ*1*10^(-9);
DVT1 = DQFG1/CFG;
DVT0+DVT1
'after 2ns'
VFG2 =CR*(VCG-(DVT0+DVT1));
EOX2 = VFG2/TOX;
JFN2 = AFN*EOX2^2*exp(-BFN/EOX2);
DQFG2 = JFN2*AINJ*1*10^(-9);
DVT2 = DQFG2/CFG;
DVT0+DVT1+DVT2
'after 3ns'
Resume calculating DVTn until reacing a certain stop time.
Plot (DVTn, time).
