Hi, I've found the next expression write it in Matlab,
Rtx = sqrt(Rt); Rtx is a matrix, and that's why I need sqrt() to operate elementwise. I've read NumPy tutorial, and I know it's possible, A set of this functions, has been provided wich optimize certain kinds of calculations on arrays. Most of this functions, such as sin, cos and sqrt are unary functions wich operate elementwise. [Numerical Python, pg. 13] but I don't know who to do it. The next error appear when I execute the code, ''' exceptions.TypeError : only length-1 arrays can be converted to Python scalars '' Thanks in advance, Mike <numpy-discussion@scipy.org>
