Matlab clamping function with separate upper & lower limits

This simple Matlab function clamps a value to lie within specified upper and lower limits. You can provide a scalar or array of values to be clamped, along with a two-element vector specifying the lower and upper bounds.

function y = clamp(x, limits)
%CLAMP Clamp a value to lie within specified limits
%   y = CLAMP(x, limits) clamps the input x so that the result y
%   lies between limits(1) (lower bound) and limits(2) (upper bound).
%
%   Inputs:
%     x      - scalar or array of numeric values to clamp
%     limits - 2-element vector [lower upper] specifying clamp range
%
%   Output:
%     y      - clamped values, same size as x

    % Validate limits
    if numel(limits) ~= 2
        error('Limits must be a 2-element vector [lower upper].');
    end
    
    lower = limits(1);
    upper = limits(2);
    
    if lower > upper
        error('Lower limit must not exceed upper limit.');
    end

    % Perform clamping
    y = min(max(x, lower), upper);
end
