ee.Image.unmix
Unmix each pixel with the given endmembers, by computing the pseudo-inverse and multiplying it through each pixel. Returns an image of doubles with the same number of bands as endmembers.
| Usage | Returns |

this: image | Image | The input image. |
endmembers | List | The endmembers to unmix with. |
sumToOne | Boolean, default: false | Constrain the outputs to sum to one. |
nonNegative | Boolean, default: false | Constrain the outputs to be non-negative. |

This is achieved by calculating the pseudo-inverse and applying it to each pixel, resulting in an output image with bands corresponding to the number of endmembers. Optional constraints include forcing the output values to sum to one ( `sumToOne`) or be non-negative (`nonNegative`). The function takes a list of `endmembers` and the input `image` to perform this.\n"]]
