For example, SimplificationMethod="vertex-clustering" simplifies the surface mesh by using the vertex-clustering method. Examples. collapse all ... Run the command by entering it in the MATLAB Command Window.The MATLAB ® software interprets the reduction factor r in one of two ways depending on its value: If r is less than 1, r is interpreted as a fraction of the original number of faces. For example, if you specify r as 0.2, then the number of faces is reduced to 20% of the number in the original patch. If r is greater than or equal to 1, then r ...Algorithms. residue first obtains the poles using roots.Next, if the fraction is nonproper, the direct term k is found using deconv, which performs polynomial long division.Finally, residue determines the residues by evaluating the polynomial with individual roots removed. For repeated roots, resi2 computes the residues at the repeated root locations. ...If you want to work in actual floating point you'll need to convert your symbolic expression into a function.
