Use dim( with ¿ to create a new matrixname of
dimensions rows × columns with 0 as each element.
{rows,columns}!dim(matrixname)
Use dim( with ¿ to redimension an existing
matrixname to dimensions rows × columns. The elements
in the old matrixname that are within the new dimensions
are not changed. Additional created elements are zeros.
Matrix elements that are outside the new dimensions are
deleted.
{rows,columns}!dim(matrixname)
Fill( stores value to every element in matrixname.
Fill(value,matrixname)
identity( returns the identity matrix of dimension rows ×
dimension columns.
identity(dimension)
