MATLAB: How to suppress answer in Matlab

MATLABsuppress

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

  • 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);
