# readers.matlab

The Matlab Reader supports readers Matlab `.mat` files. Data must be in a Matlab struct, with field names that correspond to Dimensions names. No ability to provide a name map is yet provided.

Additionally, each array in the struct should ideally have the same number of points. The reader takes its number of points from the first array in the struct. If the array has fewer elements than the first array in the struct, the point’s field beyond that number is set to zero.

Note

The Matlab reader requires the Mat-File API from MathWorks, and it must be explicitly enabled at compile time with the `BUILD_PLUGIN_MATLAB=ON` variable

Dynamic Plugin

This stage requires a dynamic plugin to operate

Streamable Stage

This stage supports streaming operations
