linealpha(x,y,varar​gin)

linealpha allows you to draw a line with transparency alpha taking
advantage of patch object.
h = linealpha(x,y)
h = linealpha(x,y,edgecolor)
h = linealpha(x,y,edgecolor,edgealpha)
h = linealpha(___,'patchparams',{Param1,Value1,...});

INPUT ARGUMENTS
x,y Vectors of the same length or arrays of the same size.
If they are arrays, each column represents one sample of data.

edgecolor EdgeColor property of the patch object.

edgealpha EdgeAloha property of the patch object.

OPTIONAL PARAMETER/VALUE PAIRS
'patchparams' You can set parameter/value pairs for the patch object by
the syntax

h = linealpha(___,'patchparams',{Param1,Value1,...});

OUTPUT ARGUMENTS
