I am looking into a octave/matlab code and find the following:
deltaT = 1; % sampling period for data
......
R = rcValues(2:2:end)/1000; % convert these also
C = rcValues(3:2:end)*1000; % convert kF to F
RCfact = exp(-deltaT./(R.*C));
What does the point (.) mean in -deltaT. and R. in this mathematical expression? Thanks
The dot operator is used to execute an operation on each element of a matrix. In your case, if deltaT and R are single elements, using the dot operator doesn't do anything. HOWEVER, if they were a matrix, then the operation would've been executed in each element of the matrix.
The operator is used with multiplication, division, and exponentiation.
