MATLAB: How i have reaction against error received of matlab

i have a for loop with a condition on receive or not receive a error of matlab program, how i can have this condition?

Best Answer

for variable = first : last
   got_error = true;
   try
     do something risky here
     got_error = false;     %only gets here if the risky thing worked
   catch ME
     do something about the error; the details of it are in ME
   end
   if got_error
     we had an error and did something with it but maybe we want to know that later
   end
 end

Modeling chemical reactions is not very difficult.

first, rewrite the chemical reaction as a differential equation.

example for reaction A->P (with rate constant 'k1')

Rate equation: Ra=-k1*Ca

ODE: dCa/dx = -Ra (x either being time or axial position in a PFR)

Now you can solve this with an ordinary ODE-solver.

You’re almost there.

if(n<0)
    str='';
else
    str=cell(n,1);
    for i=n:-1:1
        if(i==n)
            str{i}=char(ch);
        else
            temp=char(str{i+1}+1);
            str{i}=strcat(char(ch),temp);
        end
    end
end

There were three problems:

Your loop wasn’t iterating because in MATLAB, for loops by default count upward, so if the terminal value is less than the initial value, the loop is satisfied and never iterates. You need to decrement it by telling it to count down, specifying the interval to (in this instance) to be -1;
Your ‘temp’ variable subscript needs to ‘look back’ (which is to say to add 1 to ‘i’) at every iteration, and add 1 to the previous value of ‘str’;
Your strcat arguments were reversed.

A minor observation: it’s best to not use ‘i’ or ‘j’ as loop counters. They are the imaginary operators in MATLAB.
