graduate

Arguments

xmi,xma

real scalars

n1, n2

integers with default values 3,10

xi, xa

real scalars

np

integer

Description

graduate looks for the minimum interval [xi,xa] and a number of tics np such that:

xi <= xmi <= xma <= xa

xa - xi / np = k(10^n),k in [1 3 5] for an integer n

n1 < np < n2

Examples

y=(0:0.33:145.78)';
clf();
plot2d1('enn',0,y)
[ymn,ymx,np]=graduate(min(y),max(y))
rect=[1,ymn,prod(size(y)),ymx];
clf();
plot2d1('enn',0,y,1,'011',' ',rect,[10,3,10,np])
