MATLAB: How i use example.m file to another homework.m file

matlab functionusing file matlab

I prepared a matlab file showing the thermophysical properties of the air. And i want using this file's thermophysical properties for another file. How can i do that? Please help me?

You can run a script using its name. If you want to run a script inside another script, just put its name in the script. So if your first script is "thermophysical.m", you can run this from your 2nd script by calling it by name: thermophysical.

Suppose you have two scripts

script1.m and script2.m

you can call the second script from the first by just using

 script2

in the code of the first file.

Your function is calling itself without approaching any convergance or something that will allow it to end. Therefore it will run forever and eventually out of memory (hence the error). Try splitting it up into a script and a function as so:

Script:

 %creating window of plot from -5 to 50 using stepsize 0.25 for t x-axis
 %t should be on the x axis, v should be on the y axis
 k=0; 
for i= -5:.25:50
    k = k+1;
    t(k)=i;
    v(k)=vPieceWise(t(k));
end 
plot(t,v);
 
figure
plot(t,v);
hold on

Function:

%Part A: Mfile function to compute v as a function of t
function v = vPieceWise(t)
 if (t < 0)
        v = 0;
    elseif (0 <= t)&&(8<=16)
        v = -5*t+10*t.^2;
    elseif (8<=16)&&(t<=16)
        v = 624 - 3*t;
    elseif (t<=16)&&(t<=26)
        v = 12*(t-16).^2+36*t;
    elseif (26<t)
        v = 2136*exp(-0.1*(t-26));
 end
