Detailed Description

A MATLAB file open for reading data.

Access variables with var(), and get a list of variables with getVarInfoList().

This class is in fact a wrapper for MatIO C function calls. This class owns a mat_t pointer to an open file, which is open in the constructor and closed in the destructor.

Note

This C++ class is not copyable. You may pass it by value everywhere though as if it were copyable, because of C++11 move semantics.

Constructor & Destructor Documentation

File() [1/2]

Tomographer::MAT::File::File ( const std::string  fname )

inline

Open a data file for reading.

The file will be immediately open for reading. You may directly call the var(), getVarInfoList() etc. methods after constructing a File object.

Definition at line 200 of file ezmatio.h.

File() [2/2]

Tomographer::MAT::File::File ( File &&  other )

inline

Move constructor.

This object has C++11 move semantics, meaning that you can pass it around by value. Read more on C++11 move semantics for more information.

Definition at line 215 of file ezmatio.h.

Member Function Documentation

getMatPtr()

mat_t* Tomographer::MAT::File::getMatPtr ( )

inline

Direct access to the underlying C pointer used for the MatIO library.

Please be careful with this. The pointer is owned by this object, and will be free'd at the end of this object's lifetime.

Definition at line 253 of file ezmatio.h.

getVarInfoList()

std::vector< Var > Tomographer::MAT::File::getVarInfoList ( )

inline

Get a list of all variables in this data file.

The returned Var objects don't have data loaded. You must re-open them with var() to get the data.

Definition at line 1175 of file ezmatio.h.

operator=()

File& Tomographer::MAT::File::operator= ( File &&  other )

inline

Move assignment operator.

This object has C++11 move semantics, meaning that you can pass it around by value. Read more on C++11 move semantics for more information.

Definition at line 263 of file ezmatio.h.

var()

Var Tomographer::MAT::File::var ( const std::string  varname, bool  load_data = true  )

inline

Find a variable by name.

This returns a Var object with the information corresponding to the given variable.

If load_data is true (the default), then the returned Var object also contains the variable data. Otherwise, it just contains the information about the type, dimensions, etc.
