Hello,
i have the following problem, the following code doesnt work

def f2(x): return self.lgdata[2*i+1][0]*float(x)+self.lgdata[2*i+1][1]
f1=f1(self.ptdata[i])
2=f2(self.ptdata[i])
t=abs(f1-f2)

You are overriding your f1 function with a float (with
f1=f1(self.ptdata[i])), so trying to call f1(xul) later will raise this
exception.

Hi,
Thanks for getting back to me.
I'm doing element wise multiplication, basically innerProduct =
numpy.sum(array1*array2) where array1 and array2 are, in general,
multidimensional. I need to do many of these operations, and I'd like to
split up the tasks between the different cores. I'm not
It may not work for you depending on your specific problem constraints, but
if you could flatten the arrays, then it would be a dot, and you could maybe
compute multiple such dot products by storing those flattened arrays into a
matrix.

Unfortunately I can't flatten the arrays. I'm writing a library where the
user supplies an inner product function for two generic objects, and almost
always the inner product function does large array multiplications at some
point. The library doesn't get to know about the underlying arrays.

What is the rule to determine the dtype returned by numpy functions

The return type of indices will be np.intp.

Dear folks,
I have some code that stopped working with 1.6.0 and I'm wondering if
there's a better way to replace it than what I came up with. Here's a
condensed version:

but it's one that must be handled correctly

It's ok to have two different dtypes (in the sense that d1 is not d2) such
that they represent the same kind of data (in the sense that d1 == d2).
However I think your very first test should have returned True (for what
it's worth, it returns true with 1.5.1 on Windows 32 bit).
