Libsimu1b

This is the Simu1b Library version 0.1.0.

Libsimu1b was initially written to simulate the NMR behavior of a 1-spin system under free evolution or radio-frequency pulse action. This is an extension of the very simple Simu1 Library. Libsimu1b is able to compute the matrix that is associated to a rotation of given angle and axis, and to apply it to a vector. It also allows to analyze a rotation matrix to deduce its axis vector and angle value.

This is a C API. The user has to write a C program to use it. A simple executable program named demo can be built from the distribution file. The demo.c file provides an example of libsimu1b use.
