newbie, problem using ranges with function...

[luc . lefebvre]

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...
