Is there any function to solve non-linear trigonometric equations in MAT LAB other than fsolve?

What is the '@' anonymous in the '@function ' ? is there anything that we can replace the @ with ---?

implementation of fsolve function in MAT LAB simulinc is getting problem, how can we generate C code for this optimization function?

fzero if it is a function of one variable .

The trick to using anonymous functions in aa MATLAB Function Block is to create a second function that does the work.

result = MySolve(uu)

...

function result = MySolve(uu)

ff = @(xx) appropriate code

xx = fsolve(ff, x0)

...

The @ cannot be in a direct function block but it can be aa layer down .

There is no code generation support for fsolve.

You may need to convert to fminbnd or fminsearch of the square of the function .

thank you
