Ascript file called "sample_code m" has the following commands. Executing this file in MATLAB gives errors. Which of the following are the errors that we MUST fix in order for the code to execute? (multiple options may be correct, no partial credit for this question) \% sample code a=20 b=sqrt(a3) c=[ab]2 if b>a disp (b is greater than a) else disp (c) function a= test_fun (b) a=b The semicolons at end of lines 2,3, and 4is missing The if-elae does not have an end associated with it The function cest fun does not have an end associated with it The function test_ fun is located at the wrong location in the script file. The function input and output variables ( a and b ) are already defined Concatenating values of a and b tike [a bj is incorrect Matrix o cannot be squared on line 4 as it is not a square matrix
