I have a matrix of size 9*10. I want each row of the matrix get converted into a 2D matrix, like 3*3 and the coloumns which represent the number of observations, which are 10. At the end I want a 3D matrix, comprising 3*3 matrix, which will represent my data points for a particilar observation and the other dimention in coloumns should be of 10, representing the number of obsverations.

Array3D = reshape(Array2D, 3, 3, []);

@Walter Roberson Im so sorry, I have failed to convey the problem clearly. I have a matrix of 10*9 matrix, in which each row has 9 elements and each row represents one observation. So basically i need my elements(9) in each row to be a 2D matrix of 3*3. I hope I have explained clearly. I'll try the above mentioned line of code by you. if the problem isnt solved, ill reach out to you. Thank you so much.
Thank you so much for pointing out my mistake in explanning my issue.

Array3D = permute(reshape(Array2D, [], 3, 3), [3 2 1]);
