Matrix multiplication shares two features with ordinary arithmeticoperations like addition and multiplication on numbers: (a) it is usedvery heavily in numerical programs -- often multiple times per line ofcode -- and (b) it has an ancient and universally adopted tradition ofbeing written using infix syntax. This is because, for typicalformulas, this notation is dramatically more readable than anyfunction call syntax. Here's an example to demonstrate:
For example, Patricia and Paul Churchland, who have been thechampions of eliminativism, hope that connectionism is the long waitedtheory which will provide the scientific foundations of theelimination of folk psychological constructs in “psychology”(P.S. Churchland 1986, 1987; Churchland and Sejnowski 1989;P.M. Churchland 1990; P.S. Churchland and P.M. Churchland1990). Ramsey, Stich and Garon (1991) defend the claim that if certainsorts of connectionist models turn out to be right then theelimination of folk psychology will be inevitable.

We also present a simple example, showing that decimation can improve the problem-solving performance of a genetic algorithm when applied to a deceptive problem.

More powerful than changing the orders of the levels is changing their values. This allows you to clarify labels for publication, and collapse levels for high-level displays. The most general and powerful tool is . It allows you to recode, or change, the value of each level. For example, take the :
So the mapping from attitudes A ..
1d vector inputs are promoted to 2d by prepending or appending a '1'to the shape, the operation is performed, and then the addeddimension is removed from the output. The 1 is always added on the"outside" of the shape: prepended for left arguments, and appendedfor right arguments. The result is that matrix @ vector and vector@ matrix are both legal (assuming compatible shapes), and bothreturn 1d vectors; vector @ vector returns a scalar. This isclearer with examples.

This has the same fixed-point but features a zero there,so that the convergence is (the number of correct digits is roughly with each iteration). This fast approach is an example of .
The Basques are genetically distinctive - Gene Expression
Brecher was able to claim a fabulous accuracy of less than one part in 1020,improving the state-of-the-art by 10 orders of magnitude! Brecher's conclusions were based on the study of the sharpness of (GRB) received from very distant sources: In such explosive events, gamma rays are emitted from points of very different[vectorial] velocities. Even minute differences in the speeds of thesephotons would translate into significantly different times of arrival,after traveling over immense cosmological distances. As no such spread is observed, a careful analysis of the data translatesinto the fabulous experimental accuracy quoted above in support of Einstein'stheoretical hypothesis.
