setMatrix(): Return this object

[gianluca-moro]

In my Angular v14.2.3 project using node v16.14.0, I get the following
error TS7010: 'setMatrix', which lacks return-type annotation, implicitly has an 'any' return type.

To solve this, I just manually set the return type of setMatrix() in the index.d.ts to void.

I would like to propose the following changes:

• In src/image/utility/setMatrix.js, the function setMatrix() should return the this object (similar to the setChannel() function). Currently it returns nothing, which is inconsistent with other functions.
• In src/image/utility/setMatrix.js, add the return type to the setMatrix() function documentation
• Adjust the type definition in index.d.ts
