A mathematical function or command used to create visual graphs or plots on a computer, commonly used in programming languages like MATLAB.
Portmanteau of 'function' (from Latin 'functio') and 'plot' (from Middle Dutch 'plotte'), combining computational and visualization terminology that emerged in late 20th-century software development.
MATLAB's fplot revolutionized how mathematicians visualize equations—instead of hand-drawing curves for hours, scientists could see complex functions instantly, transforming pure mathematics into something visually exploratory.
