By choosing a proper dictionary, the array measurements can be well approximated by a linear combination of a few entries of the dictionary, in which the representation coefficient vector of the array measurements will be sparse.
By choosing a proper dictionary, the array measurements can be well approximated by a linear combination of a few entries of the dictionary, in which the non-zero elements of the sparse coefficient vector correspond to the targets' arrival direction.
Create a TABLECrate from a set of arrays, a dictionary, or a structured array.
This routine provides a quick means of writing out a set of arrays, a dictionary, or NumPy structured array, to a file as a table, in ASCII or FITS binary format.
If neither a dictionary or structured array is given then the data to write out is given as the col1 to coln arguments; they can be Python arrays (e.g. [1,2,3]) or numpy arrays (e.g. np.arange(4)), can be multi-dimensional (e.g. for vector columns), and can include string vectors.
A multimap is a generalization of the common map data structure, also known as a dictionary or associative array.
This routine provides a quick means of creating a TABLECrate from a set of arrays, a dictionary, or a NumPy structured array.
None of it is much help when confronted with an impatient server and a wine list the size of an unabridged dictionary, with a numbing array of unfamiliar names and prices ranging from $24 to $2,400.
An ideal dictionary would present an array of real-world examples, weighted somewhat to favor the professional over the amateur but also showing everyday usage alongside more literary examples drawn from books and movies and television and so on.
The histogram is drawn with a solid fill; this fill is then made opaque and then all color elements of the histogram set to red. or using one of the other methods - such as using a dictionary instead of an array, or the ChipsHistogram object - described in ahelp attributes.
The FITS format output is the same: a 0 for the fifth row of col1 and col2 is a vector of length 2. The write_columns routine can now accept a dictionary or NumPy structured array rather than a set of column arguments.
