A and B must be the same size.Jul 8, 2010 · MATLAB es la abreviatura de "matrix laboratory" (laboratorio de matrices). Aunque otros lenguajes de programación mayormente procesan los números de uno en uno, MATLAB® está diseñado para funcionar principalmente con matrices y arreglos completos. Todas las variables de MATLAB son arreglos multidimensionales, sin importar el tipo de datos. Remember that MATLAB is also case sensitive, so A and a are different variables. It is very easy to create large matrices. Remember to uses semicolons at the end of a command to suppress unwanted output. It is very easy to create arbitrarily large matrices. What MATLAB can handle is limited by the memory available on your computer.Matlab's logical data type does not appear to have a constructor other than the logical function itself. That being said, you can effectively typecast a double array as a logical array very easily, where all nonzero values become logic 1 and all zeros logic 0:
