Matrix and Vector Types
Matrix and Vector Types
- Matrix and vector are special data types in MQL5 which enable linear algebra operations. The following data types exist:
- matrix — a matrix containing double elements.
- matrixf — a matrix containing float elements.
- matrixc — a matrix containing complex elements.
- vector — a vector containing double elements.
- vectorf — a vector containing float elements.
- vectorc — a vector containing complex elements.
