 Nelson is an interactive, fully functional environment for engineering and scientific applications. It implements a matrix-driven language (which is largely compatible with MATLAB and GNU Octave), with advanced features such as 2-D 3-D plotting, image manipulation and viewing, a codeless interface to external C/C++/FORTRAN libraries, native support for various C types, and a host of other features.

+## Description
+
+  <p>Nelson provides a cross-platform command-line tool written in Nelson for compiling native addon modules for Nelson.</p>
+  <p>It takes away the pain of dealing with the various differences in build platforms.</p>
+
+## Example
+
+```matlab
+if ispc() && ~havecompiler()
+configuremsvc()
+end
+C_CONTENT = ["double";
+"functionC(double x)";
+"{";
+"    return x + 8;";
+"}"];
+DEST_DIR = [tempdir(), 'example_C'];
+mkdir(DEST_DIR);
+C_DEST_FILE = [tempdir(), 'example_C/demo.c'];
+filewrite(C_DEST_FILE, C_CONTENT)
+
+dlgeneratemake(DEST_DIR, 'C_DEMO', {C_DEST_FILE}, {DEST_DIR})
+[res, message] = dlmake(DEST_DIR)
+
+lib = dlopen([DEST_DIR, '/C_DEMO', getdynlibext()])
+c = dllibinfo(lib)
+
+f = dlsym(lib, 'functionC', 'double', {'double'});
+R = dlcall(f, 3) % 8 + 3
+dlclose(lib)
