Functionality available in demo version

Here you can check out what is already available and ready to use in demo version of SmartLab.

Basic Operations

All basic operators are pretty much there:

  • Matrix arithmetic operations (+, -, *, .*, /, ./, \, .\, ^, ‘).
  • Logical operations (&, |, ~, &&, ||).
  • Relational operations (<, <=, >, >=, ==, ~=).

These include matrix multiplication and solving linear equations solvers which are all optimized for modern CPUs, and use multiple CPU cores, SSE and AVX instructions.

Matrix/Array creation

Core language features


Supported types are double, single, int8, int16, int32, int64, uint8, uint16, uint32, uint64, logical, char, Complex.
