canUseGPU

Determine whether a compatible GPU is available.

📝Syntax

tf = canUseGPU()

📤Output Arguments

Parameter	Description
tf	logical: true when a compatible GPU device is available.

📄Description

tf = canUseGPU() returns true when a compatible GPU device is present and usable, and false otherwise (for example on a machine without a supported Vulkan, Metal or Direct3D 12 backend).

Use it to write code that runs on the GPU when possible and falls back to the CPU otherwise.

💡Examples

if canUseGPU()
  A = gpuArray(single(rand(1000)));
else
  A = single(rand(1000));
end
