scipy.stats.mstats.
argstoarray#
- scipy.stats.mstats.argstoarray(*args)[source]#
- Constructs a 2D array from a group of sequences. - Sequences are filled with missing values to match the length of the longest sequence. - Parameters:
- *argssequences
- Group of sequences. 
 
- Returns:
- argstoarrayMaskedArray
- A ( m x n ) masked array, where m is the number of arguments and n the length of the longest argument. 
 
 - Notes - numpy.ma.vstackhas identical behavior, but is called with a sequence of sequences.- Examples - A 2D masked array constructed from a group of sequences is returned. - >>> from scipy.stats.mstats import argstoarray >>> argstoarray([1, 2, 3], [4, 5, 6]) masked_array( data=[[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]], mask=[[False, False, False], [False, False, False]], fill_value=1e+20) - The returned masked array filled with missing values when the lengths of sequences are different. - >>> argstoarray([1, 3], [4, 5, 6]) masked_array( data=[[1.0, 3.0, --], [4.0, 5.0, 6.0]], mask=[[False, False, True], [False, False, False]], fill_value=1e+20)
