To return the dot product of two masked arrays, use the ma.dot() method in Python Numpy. The "strict" parameter sets whether masked data is propagated (True) or set to 0 (False) for the computation.This function is the equivalent of numpy.dot that takes masked values into account. The strict and out are in different position than in the method version. In order to maintain compatibility with the corresponding method, it is recommended that the optional arguments be treated as keyword only. At some point that may be mandatory.The strict parameter sets whether masked data are propagated (True) or set to 0 ... Read More

To calculate the n-th discrete difference along the given axis, use the MaskedArray.diff() method in Python Numpy. The first difference is given by out[i] = a[i+1] - a[i] along the given axis, higher differences are calculated by using diff recursively −The axis is set using the "axis" parameterThe axis is the axis along which the difference is taken, default is the last axis.The function returns the n-th differences. The shape of the output is the same as a except along axis where the dimension is smaller by n. The type of the output is the same as the type of ... Read More

This is the same as the type of a in most cases. A notable exception ... Read More

To compute the minimum of the masked array elements along a given axis, use the MaskedArray.min() method in Python Numpy −The axis is set using the "axis" parameterThe axis is the axis along which to operateThe function min() returns a new array holding the result. If out was specified, out is returned. The out parameter is alternative output array in which to place the result. Must be of the same shape and buffer length as the expected output. The fill_value is a value used to fill in the masked values. If None, use the output of minimum_fill_value(). The keepdims, if ... Read More

To calculate the n-th discrete difference along the given axis, use the MaskedArray.diff() method in Python Numpy. The "n" parameter is used to set the number of times values are differenced. If zero, the input is returned as-is.The function returns the n-th differences. The shape of the output is the same as a except along axis where the dimension is smaller by n. The type of the output is the same as the type of the difference between any two elements of a. This is the same as the type of the input in most cases. A notable exception is ... Read More
