A collection of M-Files capable of drawing a standard colored smith chart including all the labels and scales which can be found on a standard smith chart. In addition it allows other lines and circles to be drawn on the standard chart.

BASIC FUNCTION
scDraw: Draws a blank smith chart

SOME OTHER USEFUL FUNCTIONS AVAILABLE AT MATLAB COMMAND PROMPT
scRay: Draws a ray emanating from the origin towards a given point on smith chart
scMove: Move along the transmission line on smith chart
scMatchCirc: Draws the match-circle on smith chart
scInv: Inverts a given impedance (admitance) by mirroring it about the origin
scConCirc: Draws concentric circles about the origin
scArc: Draws an arc (a circle) on the smith chart passing through a given point

Tested under MATLAB 6.5

I found a bug in the function scPOI, which leads to wrong plotting results for negative reactances (using scRay). If you try to display, for example, the point
scRay(0.25-j*0.5), the negative reactance shown in the smithchart will be be zero.

To fix the bug:
In scPOI, replace

v=max(v);

by

[temp,idx]=max(abs(v));
v=v(idx);

to take care of negative numbers.

Interesting tool, but it's a bit slow

Useful! But a little bit hard to operate.

How can you draw Smith Chart for a continuous system through s=z+1/z-1 transformation?

Lina Chang

MATLAB can benefit from incorporating a toolbox like this one. Thank you for developing this tool.
