J, K, Dyalog APL

J, K, and Dyalog APL are programming languages designed for mathematical and data analysis tasks. J is a concise, expressive language optimized for numeric and array operations, emphasizing high-level mathematics. K is known for its speed and compact syntax, often used in finance and large data processing. Dyalog APL is a modern implementation of APL, a language focused on arrays and symbolic computation, featuring powerful, symbolic notation that allows complex operations to be performed succinctly. All three enable efficient handling of vast amounts of data through specialized symbols and functions, making them valuable in fields requiring advanced mathematical and data analysis capabilities.
