interpln

linear interpolation

Calling Sequence

[y]=interpln(xyd,x)

Arguments

xyd

2 row matrix (xy coordinates of points)

x

vector (abscissae)

y

vector (y-axis values)

Description

given xyd a set of points in the xy-plane which increasing abscissae and x a set of abscissae, this function computes y the corresponding y-axis values by linear interpolation.

Examples

x=[1 10 20 30 40];
y=[1 30 -10 20 40];
plot2d(x',y',[-3],"011"," ",[-10,-40,50,50]);
yi=interpln([x;y],-4:45);
plot2d((-4:45)',yi',[3],"000");
