WebMar 9, 2024 · It seems to be known issue with using syms in MATLAB function block. There is one workaround though, that is using the sym and vpassolve in another function and call that file as extrinsic. Refer to this example How to use symbolic variables and functions (Syms) in a Simulink Matlab Function? WebPlease include MATLAB code, mke sure to use syms command to give X value. Problem 1. Evaluate the following expressions in MATLAB for the given value of x. y1 = 3 * x + 2 / 4, …
