C + + invoke MATLAB engine and Eigen configuration

This week began to implement the grid watermark code, although nothing, but also can only step by step to explore the move forward.

The title of my thesis is <<watermarking 3D polygonal Meshes in the Mesh spectral domain>> the previous blog has a theoretical analysis of this paper, it seems not difficult, But it's hard to get it done. The first problem to be solved is to configure the experimental environment.

At first I was going to use eigen to decompose the eigenvalues of the Laplace matrix, so it involved the eigen configuration. Eigen is an open-source matrix operations Library, which encapsulates a large number of matrix operations, the direct invocation is very simple, its configuration is very simple.

First, configure the Eigen

1. Download Eigen
2. Extract
3. Include the Eigen directory in your project, as described in

Right click on the project, select Properties, in the VC + + directory, in the inclusion directory will be included in the Eigen directory.

?

Second, the configuration of MATLAB

1. Add included directories

Select General under C + +, add extern/include and extern/include/win32 under MATLAB installation locations in the attachment inclusion directory

?

2. Add Library

Under library Manager, select General, add Libeng.lib, Libmx.lib, and libmat.lib in additional dependencies

?

Then add the Extern/lib/win32/microsoft under the MATLAB installation location in the Attachment library directory

?

3. If you encounter the following problems during the call engine, include the path F:\Matlab_32\bin\win32 in the system variable
