Hi! I created a bad script a long time ago (months) and it has essentially destroyed my Matlab Online. I cannot run any other script without that old error occurring

The Summery is essentially it. I created a script four months ago and accidentially used the wrong syntax (&&) and it has corrupted my Matlab Online. I can run scripts with only comments, but as soon as I add anything else I get the errors back.

Help? I am so confused

Script I am running:

%% Problem 1

k1 = 10;
k2 = 5;
k3 = 8;
k4 = 10;
k5 = 20;

L1 = [1 0 0 0;
    0 1 0 0]

Error Message:

Operands to the logical AND (&&) and OR (||) operators must be convertible to logical scalar values. Use the ANY or ALL functions to

reduce operands to logical scalar values.

You probably have a third-party function named height that is interfering with correct execution.

which height

/MATLAB/toolbox/matlab/elmat/height.m

Chances are that you will get a response that shows a local height.m file.

That worked! Thank you

Question: my "height" function is nearly three years old. why did it only run errors now?

[Steven Lord]

It's possible that MATLAB Online changed something and is now calling the height function included in MATLAB where it didn't before. Because you had a height.m function available to MATLAB, that code called it instead of the one included in MATLAB and that could have caused this type of problem depending on how closely its behavior matches that of the one included in MATLAB.

Thank you very much!
