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
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
HSV | Any | Yes | — | HSV image or Nx3 HSV colormap values. |
Returns
| Name | Type | Description |
|---|---|---|
RGB | NumericArray | RGB image or colormap converted from HSV input. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:hsv2rgb:TooManyInputs | More than one input argument is supplied. | hsv2rgb: too many input arguments |
RunMat:hsv2rgb:InvalidInput | Input cannot be interpreted as an MxNx3 HSV image or Nx3 HSV colormap. | hsv2rgb: invalid input |
RunMat:hsv2rgb:Internal | RGB output tensor construction fails internally. | hsv2rgb: internal conversion failure |
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 HSVUsing 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.
