Deserializes as ComplexMatrix the CSV document contained by the specified TextReader.

Namespace:  Novacta.Analytics
Assembly:  Novacta.Analytics (in Novacta.Analytics.dll) Version: 2.0.0
Syntax
Copy
public static ComplexMatrix Deserialize(
	TextReader reader
)

Parameters

reader
Type: System.IOTextReader
The TextReader that contains the CSV document to deserialize.

Return Value

Type: ComplexMatrix
The ComplexMatrix being deserialized.
Exceptions
ExceptionCondition
ArgumentNullExceptionreader is null.
InvalidOperationException An error occurred during deserialization. The original exception is available using the InnerException property.
Remarks

This method reads CSV files created by method Serialize(TextWriter, ComplexMatrix) or one of its overloaded versions.

Examples

In the following example, the content of a well formatted CSV document is deserialized to create a matrix instance.
