hsv2rgb — Convert HSV values to RGB in MATLAB and RunMat.

hsv2rgb(HSV) converts M-by-N-by-3 image data or N-by-3 colormap rows from HSV to RGB values. Input shape and numeric range behavior follow MATLAB semantics.

Syntax

RGB = hsv2rgb(HSV)

Inputs

NameTypeRequiredDefaultDescription
HSVAnyYesHSV image or Nx3 HSV colormap values.

Returns

NameTypeDescription
RGBNumericArrayRGB image or colormap converted from HSV input.

Errors

How hsv2rgb works

  • Accepts MxNx3 truecolor images and Nx3 colormaps.
  • Hue wraps modulo 1 and saturation/value are clamped to [0,1].

Example

HSV To RGB

RGB = hsv2rgb(HSV);

Expected output:

% RGB has the same shape as HSV

Using hsv2rgb with coding agents

Open a RunMat example with live inputs, then ask the agent to explain how hsv2rgb changes the result.

Run a small hsv2rgb example, explain the result, then change one input and compare the output.

Open-source implementation

Unlike proprietary runtimes, every RunMat function is open-source. Read exactly how hsv2rgb is executed, line by line, in Rust.
