How to change the linewidth of a curve in a graph by using code?

like:

x=linspace(0,2*pi);
y=sin(x)

I want the sine curve's linewidth is 2.

Answer 1

use linewidth

x=linspace(0,2*pi); 
y=sin(x);
plot(x, y, 'linewidth',2)

Answer 2

Well, you haven't plotted anything with that code, but assuming you do:

hLine = plot( x, y );

hLine.LineWidth = 2; % Matlab R2014b or later
set( hLine, 'LineWidth', 2 ) % Matlab R2014a or earlier

or simply

hLine = plot( x, y, 'LineWidth', 2 );

all at once
