How would you define a sine function with the only argument x and parameters a(beginning of interval) b( end of interval) and m ( the number of complete Periods) Where the parameters are in the function definition?

For example I have a parameters a=2 b=6 and m=3. I am not sure how to set up the function with the parameters are in the function definition. The one way I have it set up is f=@(x,a,b,m)sin(x); There is another way to do this where the function starts as f=@(x) where a, b, and m are in the function.

Try this:

function test1
y = rand(1,M);
x = rand(1,M);
a=2;
b=6;
m=3;
PlotSin(a, b, m);

%==============================================
function PlotSin(a,b,m)
numSamples = 200; % Whatever you want.
x = linspace(a, b, numSamples);
% period * m = (b-a), so
period = abs(b-a) / m;
y = sin(2 .* pi * x / period);
plot(x, y, 'bo-', 'LineWidth', 2);
grid on;
fontSize = 24;
xlabel('x', 'FontSize', fontSize);
ylabel('y', 'FontSize', fontSize);
caption = sprintf('sin wave with %d periods between %.1f and %.1f', m, a, b);
title(caption, 'FontSize', fontSize);
% Set up figure properties:
% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);
% Get rid of tool bar and pulldown menus that are along top of figure.
set(gcf, 'Toolbar', 'none', 'Menu', 'none');
% Give a name to the title bar.
set(gcf, 'Name', 'Demo by ImageAnalyst', 'NumberTitle', 'Off')
