Hi:

I want to convert this function into matlab function:

double t_from_h(double h, double far)
{
unsigned char i;
double t, ht, error;
t = h/1100;
i = 0;
do
{
i++;
ht = h_gas(t, far);
error = abs(h - ht);
if (error > 1)
{
t = t + (h - ht)/cp_gas(t, far);
}
}
while ((error<1) || (i>30));
return t;
}

Please help me, how to do this.

1.Try following the functions logic first and make sure you understand
whats going on. (for example: what is cp_gas?)

2. Familiarize yourself with basic MATLAB
Please find more details online at:
http://www.mathworks.com/access/helpdesk/help/techdoc/learn_matlab/bqr_2pl.html
Or please paste this in the MATLAB command window:
web([docroot,'/techdoc/learn_matlab/bqr_2pl.html'])

3.Look for functional equivalents. Take a guess and search the doc.
-What would you search for in the MATLAB doc to implement the abs function
call above?
-You can use the MATLAB while loop to replace do{}while in the code above.

4.Run a few tests to ensure that the logic matches
