C1_W4 Linear Algebra

When creating a post, please add:

I am following same steps to do but I guess I am making mistake on some point or not considering can you please help out

{moderator edit - solution code removed}

Hello @Ayush_Hakhu

Use of for loop is not required

the first code line for this grader cell should
mean_vector = None where # use np.mean to get the vector of means, remember to pass the correct axis argument
mean_matrix = None # use np.repeat to repeat the mean vector n_observations times

Then calculate mean matrix by use np.reshape to reshape into a matrix with the same size as Y. Remember to use order=‘F’
mean_matrix =None

Then subtract mean_matrix from centre data. The operations are performed elementwise

incorrect code, you are suppose to use np.dot and not np.transpose

that should be x.shape


Thanks! for helping it worked
