The kernelMatrix attribute defines the list of numbers that make up the kernel matrix for the <feConvolveMatrix> element.
Values are separated by space characters and/or a comma. The number of entries in the list must equal to <orderX> by <orderY> as defined in the order attribute.
You can use this attribute with the following SVG elements:
<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
<filter id="convolveMatrix1" x="0" y="0" width="100%" height="100%">
<feConvolveMatrix kernelMatrix="1 1 0 0 0 0 0 0 -1" />
</filter>
<filter id="convolveMatrix2" x="0" y="0" width="100%" height="100%">
<feConvolveMatrix kernelMatrix="-1 0 0 0 0 0 0 0 1" />
</filter>

<list of numbers>
The list of <number>s that make up the kernel matrix for the convolution. Values are separated by space characters and/or a comma. The number of entries in the list must equal <orderX> times <orderY>.
If the result of orderX * orderY is not equal to the number of entries in the value list, the filter primitive acts as a pass through filter.
