data types

 



There are 3 basic types of numbers used in mrewave:
c terminology

 

mrewave abreviation
int integer number i
unsigned int natural number(really whole numbers) n
float real number r

Each type is qualified by a length in bytes and a complex designation. Most calculations including, additions, subtractions, multiplication, divisions and ft(s) are performed using complex r4 pairs. The following data types can be read, used and saved.

For complex numbers mrewave uses the terminology of i/q pairs (in phase/quadrature).
The i channel is the real part of the data.
The q channel is the imaginary part of the data.
r is the magnitude of the i/q pair.
q is the phase of the i/q pair..

All data is treated as a 6d array with dimensions x,y,z,t,u,v. Indexes range from [0..resolution-1]. e.g. data "i01" with a x resolution of 256 has indexes in the range of [0..255].
