MATLAB m-file Examples
Simple script
Function m-file
Ref.1)
- traparea.m
function area = traparea(a, b, h) % traparea(a, b, h) Computes the area of a trapezoid given % the dimensions a, b and h, where a and b % are the lengths of the parallel sides and % h is the distance between these sides % Compute the area, but suppress printing of the result area = 0.5 * (a + b) * h; end
m-files with "main" function
Ref.2)
- compute_trapezoid.m
function main area1 = traparea(1,2,3) disp(area1) end function area = traparea(a, b, h) % traparea(a, b, h) Computes the area of a trapezoid given % the dimensions a, b and h, where a and b % are the lengths of the parallel sides and % h is the distance between these sides % Compute the area, but suppress printing of the result area = 0.5 * (a + b) * h; end
Ref.3)
- quads.m
function main() [root1, root2] = quadratic(1, sqrt(2), 1); disp(root1); disp(root2); end function [x1, x2] = quadratic(a, b, c) % [x1, x2] = quadratic(a, b, c) % Return the roots of a*x^2 + b*x + c. % Roots may be complex. d = disc(a, b, c); x1 = (-b + d) / (2*a); x2 = (-b - d) / (2*a); end function dis = disc(a,b,c) % dis = disc(a,b,c) % Return the discriminant of a, b, c. dis = sqrt(b^2 - 4*a*c); end
Returning multiple values
Ref.4)
- c_to_p.m
function main [r, th] = cart2plr(30, 40); disp(r); disp(th); end function [r, theta] = cart2plr(x, y) % cart2plr Convert Cartesian coordinates to polar coordinates % % [r, theta] = cart2plr(x, y) computes r and theta with % % r = sqrt(x^2 + y^2); % theta = atan2(y,x); r = sqrt(x^2 + y^2); theta = atan2(y,x); end
