The following Matlab project contains the source code and Matlab examples used for circuit analysis toolbox. FEATURES   * Numerical analysis with only Matlab   * Symbolic analysis by adding the       Symbolic Math Toolbox   * Extensive help with the "help" and "doc"       commands   * Extensive Web browser help with several       examples   * Independent voltage and current source       components   * Resistor, inductor, and capacitor components   * Current dependent current source,       voltage dependent current source,       voltage dependent voltage source       components   * Component properties include type,       designator, value,       plus tolerance, and       negative tolerance   * GUI editing of component properties   * Any node can be designated as the       reference (or ground) node   * Each node carries and "accessible" property       indicating whether it has measurement       access   * Branch currents and node voltage results       accessed by component designator       and node name (not vector row number)   * Bode plots of any branch current or node       voltage with a single command   * Monte Carlo analysis with bode plots   * Perturbation analysis functions   * With the Symbolic Math Toolbox, writes       the equations for branch currents and node       voltages.
