Pi is a constant, an irrational number and its notation represent the sixteenth letter of the Greek alphabet, though its value is equal to the ratio of a circle’s circumference to its diameter.
However, a Muslim scientist Abu-Abdullah Muhammad Ibn Musa al-Khwarizmi the founder of algebra ( derived from the Arabic word El-Jabr ), arithmetic, and trigonometry, an astronomer, and a geographer C850 studied and proved Pi’s...
Iterative, robust fit of the exact equation of a circle to xy data. Outliers are identified based on multiples of current standard deviation and "set aside". The interative solution proceeds until there are no remaining outliers. Returns...

This function uses rectangle command to plot a circle. The center is to be given in a vector form and radius is a non-negative number.
This program checks whether a point (x,y) lies inside,outside or on a circle defined by 3 other points.
Syntax: iscircle(X,Y,x,y), where X=[x1 x2 x3] and Y=[y1 y2 y3]. Thus, a circle can be made out of these 3 points-->(x1,y1),...
Sometimes when visualising the results of a cluster analysis using a dendrogram, showing all points in the dataset results in a rather cluttered plot. This can sometimes be improved upon by using a polar dendrogram, which spreads out the leaf...
