newbie, problem using ranges with function... |

Hi,
I wrote this script:
#-------start-------
function M=f(x)
M=0;
if (x<6)
M=250*x;
else
M=250*x-2.5*250*(x-6);
endif
endfunction
x=(0:.1:10)'
data=[x, f(x)]
gplot data
#-------finish------
When I test the function f(x) manually (ie. f(0)=f(10)=0, f(6)=1500)
all is OK. When I do f(x) as above I get an output that is 3750
decreases monotonically by 37.5 for each value of x which is obviously
wrong.
Interestingly if I do sin(-pi:.1:pi) I get what would be expected.
There is obviously something that I am not getting...
