Explain GPU computing and acceleration in MATLAB
Updated May 17, 2026
Short answer
GPU computing in MATLAB accelerates massively parallel numerical operations using CUDA-enabled graphics processing units.
Deep explanation
Graphics Processing Units (GPUs) contain thousands of smaller processing cores optimized for parallel workloads. Unlike CPUs, which excel at sequential task execution, GPUs are designed for high-throughput numerical operations.
MATLAB supports GPU acceleration through:
- gpuArray
- Parallel Computing Toolbox
- Deep Learning Toolbox
- CUDA code generation
GPU acceleration is particularly effective for:
- Matrix multiplication
- Deep learning
- Image processing
- FFT computations
- Monte Carlo simulations
- Scientific simulations
The typical GPU workflow is:
- Transfer data to GPU memory
