READ_SPR

The READ_SPR function reads a row-indexed sparse array from a specified file and returns the array as the result. Row-indexed sparse arrays are created using the SPRSIN function and written to a file using the WRITE_SPR function.

This routine is written in the IDL language. Its source code can be found in the file read_spr.pro in the lib subdirectory of the IDL distribution.

Calling Sequence

Result = READ_SPR( Filename )

Arguments

Filename

A scalar string specifying the name of the file containing a row-indexed sparse array.

Example

Suppose we have already saved a row-indexed sparse array to a file named sprs.as , as described in the documentation for the WRITE_SPR routine. To read the sparse array from the file and store it in a variable spr s, use the following command:

sprs = READ_SPR('sprs.as')
