For JavaScript, the orderX property indicates the number of columns in the kernelMatrix. For HTML, the order attribute is used to set both orderX and orderY, as described next.

Indicates the number of cells in each dimension for kernelMatrix. The values provided must be integers greater than zero. The first number, orderX, indicates the number of columns in the matrix. The second number, orderY, indicates the number of rows in the matrix. If orderY is not provided, it defaults to orderX.

A typical value is order="3". It is recommended that only small values (such as 3) be used; higher values may result in very high CPU overhead and usually do not produce results that justify the impact on performance.

If the order attribute is not specified, the effect is as if a value of 3 were specified.
