Create a SAS dataset(s) from a SAS matrix catalog file


 %mat2dat( input libref , matrix catalog name ,
output libref );

Description

MAT2DAT creates a SAS dataset out of each matrix in a SAS matrix catalog file. This is especially useful if you have to transfer the matrix data from one operating system to another since SAS catalog files can only be read into SAS on the operating system the file was created on where SAS datasets can be read on any operating system. To convert the SAS datasets back to a SAS catalog file again, use the DAT2MAT SAS macro.

Options

NOTE: The parameters have to be specified in the order of this list.

Parameters	Explanation
(1st) *input_libref*	The libref where the input SAS matrix catalog file exists.
(2nd) *catalog_name*	The name of the input SAS matrix catalog file (without the file extension: "`.sas7bcat`").
(3rd) *output_libref*	The libref where the output SAS dataset will be saved to.

How to invoke MAT2DAT:

Using the MAT2DAT macro requires that you understand how to use the %include statement and that you know how to call a SAS macro.

 %include "LOCATION AND NAME OF A FILE THAT CONTAINS SAS CODE";

For example, if you have copied this file to "C:\SASmacros\", then you tell SAS about this macro by adding the following line to your SAS program:

 %include "C:\SASmacros\mat2dat.sas";

The include statement makes SAS aware of the MAT2DAT macro which is in the file mat2dat.sas. You call the macro by adding this to your code:

  %mat2dat( LIB_IN , CATALOG_FILE , LIB_OUT );

Examples


   libname LIB_IN "C:\wherever your matrix_data.sas7bcat file is\";

   libname LIB_OUT "C:\wherever you want your datasets stored\";
 
   %include "C:\wherever you put mat2dat.sas\mat2dat.sas";
 
   %mat2dat(LIB_IN , matrix_catalog , LIB_OUT);

The above invocation of MAT2DAT expects to find the SAS matrix catalog file:

    matrix_catalog.sas7bcat

in the LIB_IN library. If the matrix catalog file contains the matrices:

    mat1 mat2 mat3

then it will create the SAS datasets:

    matrix_catalog_mat1.sas7bdat
    matrix_catalog_mat2.sas7bdat
    matrix_catalog_mat3.sas7bdat

in the LIB_OUT library.
