You can use scipy.stats.truncnorm, can't you? Unless I misread, you want
to sample a normal distribution but with generated values only being
within a specified range? However you also say you want to do this with
triangular and log normal and for these I presume the easiest way is to

I have used both linear least squares and radial basis functions as a
proxy equation, calculated from the results of computer simulations
which are calculating some objective function value based on a number of
varied input parameters.

I'm reading a file which contains a grid definition. Each cell in the
grid, apart from having an i,j,k index also has 8 x,y,z coordinates.
I'm reading each set of coordinates into a numpy array. I then want to
add/append those coordinates to what will be my large "points" array.
Due to the orient
I'm using FortranFile to read a binary Fortran file.
It has a bit of header data at the top of the file which I'm reading
with a combination of readString and struct.unpack
This is then followed by a number of lines/records, each of which has 20
double precision reals/floats.

Hi
I'm using FortranFile on 32 bit XP.
The first record in the file has both 32 bit integer values and double
precision float values.
I've used readInts('i') to read the data into what I presume is a 32-bit
integer numpy array.
Items 0 and 1 of the array are the first double precision value.

Hi
No doubt asked many times before so apologies
I'm pulling a subset array out of a data array where I have a list of
the indices I want (could be an array rather than a list actually - I
have it in both).
Potentially the number of points and the number of times I do this can

Hi
I'm using npfile which is giving me a deprecation warning. For the time
being I want to continue using it but I would like to suppress
the warning messages. Is it possible to trap the deprecation warning but
still have the npfile go ahead?
Thanks

I've created an array of strings using something like
stringarray=self.karray.astype("|S8")
If the array value is a Nan I get "1.#QNAN" in my string array.
For cosmetic reasons I'd like to change this to something else, e.g.
"invalid" or "inactive".
My string array can be up

Hi numpy/scipy users,
I'm looking to add some basic goodness-of-fit functions/plots to my app.
I have a set of simulated y vs time data and a set of observed y vs time
data.
The time values aren't always the same, i.e. there are often fewer
observed data points.
Some variables will be in a 0.

I have an array (porvatt.yarray) of ni*nj*nk values.
I want to create two further arrays.
activeatt.yarray is of size ni*nj*nk and is a pointer array to an active

Ok... I'm using Traits and numpy.

I have NI,NJ,NK cells in the I,J,K directions so I have NI*NJ*NK cells

I have data arrays with a value for each cell in the grid.
I'm going to store this as a 1D array, i.e. 1ncells where

these read/write methods simply read/write numpy arrays to a
binary file which contains one or more numpy arrays (and nothing else).
(2) replace my binary files iwith either HDF5 or PyT

My app reads in one or more float arrays from a binary file.
Sometimes due to network timeouts etc the array is not read correctly.
What would be the best way of checking the validity of the data?
Would some sort of checksum approach be a good idea?
Would that work with an array of floating poin
