SAS/IML 12.3 introduced the following functions and subroutines for data analysis:
- BLANKSTR function
-
returns a blank string of a specified length.
- COL function
-
returns a matrix
, which is the same size as the input matrix, such that ![$M[i,j]=i$](images/imlug_whatsnew90002.png)
.
- CORR2COV function
-
scales a correlation matrix into a covariance matrix.
- COV2CORR function
-
scales a covariance matrix into a correlation matrix.
- EXPANDGRID function
-
returns a matrix that contains all combinations of elements from specified vectors.
- ISEMPTY function
-
returns 1 if the argument is an empty matrix (zero rows and columns) and 0 otherwise.
- MAGIC function
-
returns a magic square of a given size.
- RANDFUN function
-
returns a matrix of random numbers from a specified distribution.
- ROW function
-
returns a matrix
, which is the same size as the input matrix, such that ![$M[i,j]=j$](images/imlug_whatsnew90003.png)
.
In addition, each of the following subroutines creates an ODS statistical graph from data in a SAS/IML matrix. The graph is displayed in the current ODS destination.
- BAR call
-
creates a bar chart.
- BOX call
-
creates a box plot.
- HISTOGRAM call
-
creates a histogram.
- SCATTER call
-
creates a scatter plot.
- SERIES call
-
creates a series plot.
