Scan scalars for built in types
Subclass of Zlib::Error when zlib returns a Z_DATA_ERROR.
Usually if a stream was prematurely freed.
Objects of class File::Stat encapsulate common status information for File objects. The information is recorded at the moment the File::Stat object is created; changes made to the file after that point will not be reflected. File::Stat objects are returned by IO#stat, File::stat, File#lstat, and File::lstat. Many of these methods return platform-specific values, and not all values are meaningful on all systems. See also Kernel#test.
exception to wait for writing by EAGAIN. see IO.select.
exception to wait for writing by EWOULDBLOCK. see IO.select.
exception to wait for writing by EINPROGRESS. see IO.select.
Exception raised when there is an invalid encoding detected
The error thrown when the parser encounters illegal CSV formatting.
A CSV::Table is a two-dimensional data structure for representing CSV documents. Tables allow you to work with the data by row or column, manipulate the data, and even convert the results back to CSV, if needed.
All tables returned by CSV will be constructed from this class, if header row processing is activated.
Raised when the provided IP address is an invalid address.
Raised when the address family is invalid such as an address with an unsupported family, an address with an inconsistent family, or an address who’s family cannot be determined.
Raised when the address is an invalid length.
Eigenvalues and eigenvectors of a real matrix.
Computes the eigenvalues and eigenvectors of a matrix A.
If A is diagonalizable, this provides matrices V and D such that A = V*D*V.inv, where D is the diagonal matrix with entries equal to the eigenvalues and V is formed by the eigenvectors.
If A is symmetric, then V is orthogonal and thus A = V*D*V.t
