Detailed Description

Arbitrary rescales value(s) from one range (A:B) to another (A1:B1).

Rescales values from A:B to A1:B1, or (if only A1:B1 are provided) from 0:1 to A1:B1.

Note

Elemental functions.

Member Function/Subroutine Documentation

rescale_1()

elemental real(srp) function commondata::rescale::rescale_1	(	real(srp), intent(in)	value_in,
		real(srp), intent(in)	A1,
		real(srp), intent(in)	B1
	)

Rescale a real variable with the range 0:1 to have the new range A1:B1.

Warning

The function does not check if value_in lies within [0:1].

Note

Code for wxMaxima equation solve:

solve(  [a1=0*k+b, b1=1*k+b] ,[k,b] );

rescale_full()

elemental real(srp) function commondata::rescale::rescale_full	(	real(srp), intent(in)	value_in,
		real(srp), intent(in)	A,
		real(srp), intent(in)	B,
		real(srp), intent(in)	A1,
		real(srp), intent(in)	B1
	)

Rescale a real variable with the range A:B to have the new range A1:B1.

Linear transformation of the input value value_in such k * value_in + beta, where the k and beta coefficients are found by solving a simple linear system: . It has this solution:

Warning

The function does not check if value_in lies within [A:B].

Note

Code for wxMaxima equation solve:

solve(  [a1=a*k+b, b1=b*k+b] ,[k,b] );
