How do I suppress answer in Matlab?

Hi, I'm trying to calculate e^x for some value of x using the taylor expansion approximation

T_n(x) = Sum (x^k/k!)

And I have managed to do this using the following m-file

function T = findexp(x,n) %findexp, function to evaluate e^x T(1)=1; for i = 2:n+1 T(i) = T(i-1)+x^(i-1)/(factorial(i-1)); if i == n+1 fprintf(1,'T(%d) = %1.15e\n',x,T(i)); end end

However, when I then type findexp(1,25) for example the output is

T(1) = 2.718281828459046e+000

ans =

Columns 1 through 8

    1.0000    2.0000    2.5000    2.6667    2.7083    2.7167    2.7181    2.7183

Columns 9 through 16

    2.7183    2.7183    2.7183    2.7183    2.7183    2.7183    2.7183    2.7183

Columns 17 through 24

    2.7183    2.7183    2.7183    2.7183    2.7183    2.7183    2.7183    2.7183

Columns 25 through 26

    2.7183    2.7183

How do I suppress the columns and just show the T(1) part.

Sorry I realise this is a really amateurish question I just have done very little Matlab programming before.

Thanks in advance

I have the same problem with optimizer function called "fmincon" as per the help files the output of this functon can not be switched off. You can supress the final result but not the intermediate output generated by the calculations. I have tried all kinds of options associated with this function but I still can not supress the output. Is there any way to supress thd output of an entire matlab code on command window? I am already storing the output variables I need so it doesnt matter if I get output on command window or not.

Just don't define output in the function definition line, or when you call the function, add semicolon at the end, i.e.,

findexp(1,25);

That's great thank you
