How do I fix this code? It says "Conversion to function_handle is not possible" on the line f(×) = (x^4) - (10*x^3) + 5

xo = 1; dx = xo; dx = 0.00001; f(x) = (x^4) - (10*x^3) + 5;

P = 1; While P < 0; x1 = x; if f(x1) = 0; exactroot = 0; x2 = x1; P = 0; else x2 = x1 + dx; P = f(x1)*f(x2); x = x2; end end

x1 = a; x2 = b

First, fix the typographical errors. Remember that MATLAB is case-sensitive.

Second, see the documentation section on Anonymous Functions.

About that sir, sorry I just typed my code on my phone😅. Second i couldn't understand that part. This maybe my 2nd time creating code but I haven't really taken the programming course yet. Just youtube😅 I was mistakenly enrolled to application of programming without taking its prerequisite course first. Anyways thankyou😊

Ar, in that case, I highly recommend you complete the Matlab Onramp course:

https://www.mathworks.com/learn/tutorials/matlab-onramp.html

It's free, and teaches you all the basics of Matlab you need to get started.

My pleasure!

Function handles are important in MATLAB. See What Is a Function Handle? for an extended discussion.

For an introduction to MATLAB see Getting Started. Also see Learn with MATLAB and Simulink Tutorials.

Remember that none of us (well, at least most of us) were not born knowing how to program computers in any programming language!

Alright thank you 😊
