This demo consists of a m-file script (fixed_point_atan2_using_cordic.m) and a m-file function (atan2_fixpt.m). The script contains a step-by-step explanation of how a four quadrant arctan can be calculated using a CORDIC (COordinate Rotation DIgital Computer) algorithm. The first part shows the...

Electrohydraulic servoactuators provide one of the best controllers from the point of view of precision and speed of response. They are used to control wide range of mechanical parameters, such as the displacement, angular displacement, strain, force, and others. They incorporate, mostly, a...

An ADCARRAY object usually contains a memmapfile object, together with a scale and offset to convert the values stored on disc (and pointed to by the memmapfile object) to real world numbers which are returned as double precision. These can also be transformed by a function pointed to by a handle...

The m-file imsl2c.m (IMSL to 'C') automates the process of writing the source code for C MEX files which, in turn, call routines in the IMSL numeric libraries. These libraries are included in the professional version of DEC's Digital Visual Fortran. The mat-file imsl.mat contains structures that...
