like:
x=linspace(0,2*pi);
y=sin(x)
I want the sine curve's linewidth is 2.

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