Hi,
I'm trying to do something like this:
all_a = ones(1, 20);
for k = 1:20
function y = f(t)
x = mod(t, pi);
s = t*(pi-t);
y = s*cos(k*t);
endfunction
a = (2/pi) * quad('f', 0, pi);
all_a(k) = a;
endfor
But I get:
error: `k' undefined near line 8 column 15
error: evaluating binary operator `*' near line 8, column 16
error: evaluating argument list element number 1
error: evaluating binary operator `*' near line 8, column 10
error: evaluating assignment expression near line 8, column 7
error: called from `f'
error: evaluating for command near line 4, column 1
error: near line 13 of file `/srv/www/studie/s_en_t/opg15.m'
How do I pass the 'k' from the for loop into the function and calculate
the integration? I'm trying to calculate real fourier coefficients. Any
hints?
yours,
Gerrit.
