MATLAB: How to suppress answer in Matlab

Question

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

Answer 1

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);
