Hi, I have many vtk files storing the velocity field information, which is created in Paraview. Now I want to import them into Matlab to do the proper orthogonal decomposition, so I need to convert the data into matrix. Is there any way to read the raw data files with the format of VTK into Matlab? Thanks!!
File format is unsupported for uploading, but it has the following structure:
