The dimensions of the matrices must be the same. This operator multiplies each element of the first matrix by the corresponding element of the second matrix. Perform polynomial multiplication and simplify the results, show that ( x - 1 ) ( x + 1 ) ( x 2 + x + 1 ) ( x 2 + 1 ) ( x 2 - x + 1 ) ( x 4 - x 2 + 1 ) simplifies to x 1 2 - 1. Multiply the matrices by using the elementwise multiplication operator. A way to express this in Matlab could be: syms lambda real sol Z/ (P-I) + lambda null ( (P-I)')' sol - (lambdasigma)/ (sigma - 1), lambda Share. Most mathematical expressions can be represented in different, but mathematically equivalent forms and the Symbolic Math Toolbox supports a number of operations, including factoring or expanding expressions, combining terms, rewriting or rearranging expressions, and simplification based on assumptions. Remember that the complete solution of a linear system of equations is the sum of the particular solution + a linear combination of the elements of the null space. The Symbolic Math Toolbox supports the Formula Manipulation and Simplification of mathematical functions. Use vpa and digits to approximate symbolic results with the required.
