+JavaCPP Presets for OpenBLAS
+============================
+
+Introduction
+------------
+This directory contains the JavaCPP Presets module for:
+
+ * OpenBLAS 0.2.18  http://www.openblas.net/
+
+Please refer to the parent README.md file for more detailed information about the JavaCPP Presets.
+
+
+Documentation
+-------------
+Java API documentation is available here:
+
+ * http://bytedeco.org/javacpp-presets/openblas/apidocs/
+
+∗ The JNI bindings actually link with [Intel MKL](https://software.intel.com/intel-mkl) instead if found on the "java.library.path".
+
+
+Sample Usage
+------------
+Here is a simple example of LAPACK ported to Java from this C source file:
+
+ * https://github.com/bitfusionio/OpenBLAS/blob/master/lapack-netlib/lapacke/example/example_DGELS_rowmajor.c
+
+We can use [Maven 3](http://maven.apache.org/) to download and install automatically all the class files as well as the native binaries. To run this sample code, after creating the `pom.xml` and `src/main/java/ExampleDGELSrowmajor.java` source files below, simply execute on the command line:
+```bash
+ $ mvn compile exec:java
+```
+
+### The `pom.xml` build file

+   LAPACKE Example : Calling DGELS using row-major order
+   =====================================================
+ 
+   The program computes the solution to the system of linear
+   equations with a square matrix A and multiple
+   right-hand sides B, where A is the coefficient matrix
+   and b is the right-hand side matrix:
+  
+   Description
+   ===========
+ 
+   In this example, we wish solve the least squares problem min_x || B - Ax || 
+   for two right-hand sides using the LAPACK routine DGELS. For input we will
+   use the 5-by-3 matrix
+
+         ( 1  1  1 )
+         ( 2  3  4 )
+     A = ( 3  5  2 )
+         ( 4  2  5 )
+         ( 5  4  3 )
+    and the 5-by-2 matrix
+
+         ( -10 -3 )
+         (  12 14 )
+     B = (  14 12 )
+         (  16 16 )
+         (  18 16 )
+    We will first store the input matrix as a static C two-dimensional array,
+    which is stored in row-major order, and let LAPACKE handle the work space
+    array allocation. The LAPACK base name for this function is gels, and we 
+    will use double precision (d), so the LAPACKE function name is LAPACKE_dgels.
+
+    thus lda=3 and ldb=2. The output for each right hand side is stored in b as
+    consecutive vectors of length 3. The correct answer for this problem is 
+    the 3-by-2 matrix
+
+         ( 2 1 )
+         ( 1 1 )
+         ( 1 2 )
+
+    A complete C program for this example is given below. Note that when the arrays
+     are passed to the LAPACK routine, they must be dereferenced, since LAPACK is
+      expecting arrays of type double *, not double **.
+
