Pooja Lalan submitted a Comment to Problem 44934. Plot Damped Sinusoid

Omkar- Thanks for pointing out the issue with the test suite. I have modified messages to errors when the solution has no plot or too many plots. The solutions will be rescored.

Hi Ali, this is because the output m is expected to contain the minimum value of the input y, not a handle to the plot. Hope that helps.

@Hugo, check syntax for load in the documentation https://www.mathworks.com/help/matlab/ref/load.html Specifically, check what to expect when assigning output from load to a variable.

Thanks Ian for pointing out the error. I have updated the description to use the appropriate name for the marker.

The output is expected to be a column vector, whereas your code returns a table.

Hint 1: You need not know or use anything about the value of pixels in this image. Hint 2: All you have to do is get a subset of a matrix in MATLAB (the matrix, in this case, represents an image).

Pooja Lalan submitted a Comment to Problem 44950. Calculate Inner Product

If the output x*y is not assigned to any variable, MATLAB assigns it to the variable ans by default. In this solution, z has been replaced with ans in the function definition to return the unassigned output.

Thank you! Modified the problem statement.

Mohamed, the check plotted data error suggests that the data you are plotting in the plot command does not match the data you are expected to plot i.e. your y and m variables. The red star marker must be on the minimum value of any given input signal y.

The problem specifies that the input hw is a matrix with two columns (not a table). So, the error is saying that you cannot use dot indexing on a matrix.

The expected output is a column vector containing ALL the bmi values, whereas your code returns a single bmi value i.e. the last one. Hope that helps!

Thanks Paresh. Your approach is a valid solution that the tests were not designed to evaluate previously. I have now modified the tests to pass this alternative approach. However, there are two other issues with this solution, which you will have to resolve: 1. The color 'b' expected for the line is not the same as the default blue color the MATLAB uses. 2. The output is expected to be the minimum value of y, not a handle to the plot. I have also added appropriate messages for the tests. Thanks again!

Hi Asif, the output from the function is expected to be only the minimum value of vector y; whereas your code returns both - the minimum value of y and also the corresponding t. This is causing the last test to fail. I will modify the tests to make it clearer. You should pass the tests if you set m = ymin

Thank you Payam. I assume you meant specifying the order of the inputs explicitly. I have updated the description to make it clearer.

Andrew, I suspect that this is failing the second test because the new plot lines are being plotted over the previous plot (from test 1). It is always a good practice to use 'hold off' (here and in MATLAB, generally) to stop plotting over old plots. Having said that, I will consider adding a 'figure' command to the tests, since Cody does not display the plots and it is difficult to debug this particular problem without seeing the plots.
