I am looking to implement a resampling algorithm for a 2D array(it could be grayscale image or some 2D array of floating point values).
Basically I have a large (could get as large as 100,000-150,000 values) data set of 4-byte inputs and their corresponding 4-byte outputs. The inputs aren\'t guaranteed to be unique (which isn\'t reall
Is there a quick way of replacing all NaN values in a numpy array with (say) the linearly interpo开发者_开发问答lated values?
One of the things sorely lacking from iOS is the ability to set keys on an attribute/attributes and interpolate between them using a spline. Has anyone thought about this and/or found an approach to g
I use scipy\'s griddate-function for interpolation. What does the following error message means which appears when python is executing the griddata-function?
I have a set of coordinates representing the 3d positions of a number of objects. These points are taken from a simulation of a 3-d cube. What I need to do is to make a 3d grid on the cube, and then t
How do I get Perl\'s 开发者_Go百科qx function to execute with my $opt variable? Before (works): my @df_output = qx (df -k /tmp);
in Python I want to interpolate some data using scipy.interpolate.griddata(x,y,z,xi,yi). Since I want my unequal spaced original data on the X-Y grid map on an equal spaced XI-YI grid I have to use a

I have a NxN grid of values and a 2xM list of x,y data points to be interpolated onto that grid (obtained from the output of countour on a similar grid of values).
