public class MatrixFunctionTable
extends FunctionTable

A function table with some matrix functions. Defines

• det - the determinate of a matrix
• trace - the trace of a matrix
• trans - transpose of a matrix
• id - creates an identity matrix id(3) is a 3 by 3 matrix
• zeroMat - creates a matrix of zeros zeroMat(3,2) creates a 3 by 2 matrix
• zeroVec - creates a vector of zeros zeroVec(3) creates a 3 element vector
• size - finds the length of a vector or the vector with rows and columns of a matrix
• inv(m) - find the inverse of m
• v=solve(m,u) - find solution of m * v = u

shallowCopy

public FunctionTable shallowCopy()

Description copied from class: FunctionTable

Returns a new shallow copy of this function table. Calls the FunctionTable.threadSafeMapCopy() method to ensure the table is safe to use a separate thread. All subclasses should override this method to create a function table of the matching type. A typical implementation would be

 @Override
 public FunctionTable shallowCopy() {
     Map<String,PostfixMathCommandI> newMap = this.threadSafeMapCopy();
     return new myFunctionTable(newMap);
 }
 

using the FunctionTable.threadSafeMapCopy() method to return a copy of the map of functions and a constructor taking this map which uses the FunctionTable(Map) constructor.

Overrides:

shallowCopy in class FunctionTable

Returns:

a new shallow copy of this function table
