MATLAB: What DOF in matlab mean

Question

I get a code as follow :

% Degrees of freedom

% Assemble a column matrix containing all DOFs at which stiffness is

% present in the model:

DOF=getdof(Elements,Types);

However, I don't know what DOF mean

I guess. It is degree of freedom.

Please explain for me DOF ?

Thank you very much

Answer 1

The number and types of joints, gears, and constraints in a mechanism partially determine its mobility—the total number of degrees of freedom, or DoFs, that the mechanism provides and therefore the minimum number of input variables needed to fully constrain its configuration. refer https://in.mathworks.com/help/physmod/sm/ug/mechanism-degrees-of-freedom.html
