COMBINE_MATRIX

This is part of the adjmat module

Calculate the sum of a number of matrices

Examples

Glossary of keywords and components

Compulsory keywords

PERIODIC	if the output of your function is periodic then you should specify the periodicity of the function. If the output is not periodic you must state this using PERIODIC=NO
COEFFICIENTS	( default=1.0 ) the coefficients of the arguments in your function
PARAMETERS	( default=0.0 ) the parameters of the arguments in your function
POWERS	( default=1.0 ) the powers to which you are raising each of the arguments in your function

Options

SERIAL	( default=off ) do the calculation in serial. Do not parallelize
NORMALIZE	( default=off ) normalize all the coefficients so that in total they are equal to one
ARG	the input for this action is the scalar output from one or more other actions. The particular scalars that you will use are referenced using the label of the action. If the label appears on its own then it is assumed that the Action calculates a single scalar value. The value of this scalar is thus used as the input to this new action. If * or *.* appears the scalars calculated by all the proceeding actions in the input file are taken. Some actions have multi-component outputs and each component of the output has a specific label. For example a DISTANCE action labelled dist may have three components x, y and z. To take just the x component you should use dist.x, if you wish to take all three components then use dist.*.More information on the referencing of Actions can be found in the section of the manual on the PLUMED Getting Started. Scalar values can also be referenced using POSIX regular expressions as detailed in the section on Regular Expressions. To use this feature you you must compile PLUMED with the appropriate flag.. You can use multiple instances of this keyword i.e. ARG1, ARG2, ARG3...
