DH Parameter Model with MATLAB Symbolic Function Implementation

This function code utilizes MATLAB's symbolic function capability to generate DH matrices either by manually inputting symbolic DH parameter matrices or importing DH parameter tables from Excel files. The resulting DH matrix can be used for further transformation matrix calculations in MATLAB, and specific numerical values can be substituted into the transformation matrices to compute concrete DH matrix values. The implementation involves symbolic variable handling, matrix multiplication operations, and automated parameter parsing from spreadsheet files.
