Blocks CombiTable1Factor and CombiTable2Factor implement the way EHTPlib uses matrices to determine components' behaviour such as torque limitation, optimal speeds, ICE consumptions, etc.
CombiTable1Factor is based on a MSL CombiTable1Ds, CombiTable2Factor on CombiTable2Ds.
These matrices can be directly written on the input mask, or taken from a file.
When they are taken from a file, it is very convenent to use factors on matrix inputs and output. This allows for instance to compensate usage of rpm instead of rad/s for speeds, or to re-use matrices in machines different from those they were originally written for, scaling input axes and ouptut.
For instance one could have a fuel consumption map of an ICE; which is adequate for a full family of engines: using these factors, it can be scaled to different speed/torque ranges, and omothetically varied also vertically (e.g. consumptions can be reduced to 90% by multiplication with an output factor equal to 0.9).
When matrix is not from a file, factors are automatically set to 1, and the input matrix is used without changes. When, instead, it is taken from a file, the two inputs are mutiplied by u1Factor and u2Factor respectively, and output by yFactor.
