+This page documents the routine `PDAF_generate_rndmat` of PDAF.
+
+The routine returns a random matrix with special properties. 
+
+The interface is the following: 
+{{{
+  SUBROUTINE PDAF_generate_rndmat(dim, rndmat, mattype)
+}}}
+with the following arguments:
+{{{
+  INTEGER, INTENT(in) :: dim         ! Size of matrix rndmat
+  REAL, INTENT(out)   :: rndmat(dim, dim) ! Matrix
+  INTEGER, INTENT(in) :: mattype     ! Select type of random matrix:
+                                     !   (1) orthonormal random matrix
+                                     !   (2) orthonormal with eigenvector (1,...,1)^T
+}}}
+
+**Note:**
+ * This matrix is e.g. used internally by PDAF_sampleens for second-order exact sampling.
