[Numpy-discussion] mean of two or more arrays while ignoring a specific value

[Greg Fiske]

Dear list,

 

I'm learning to work with numpy arrays.  Can somebody explain how to get the
average of two separate arrays while ignoring a user defined value in one
array?

 

For example:

>>>a = numpy.array([1,5,4,99])

>>>b = numpy.array([3,7,2,8])

 

Ignoring the value 99, the result should be an array like c= ([2,6,3,8])

 

Thanks for any advice,

 

Greg
