How to represent e -t 2 in MATLAB

Question

I am a beginner in MATLAB  and I need to represent e -t2    I know that  for example  to represent ex I use exp x   and I have tried the following  1  tp t 2    tp t t     x exp -tp    2  x exp -t 2    3  x exp - t t     4  x exp -t  exp -t    What is the correct way to do it

If t is a matrix  you need to use the element-wise multiplication or exponentiation  Note the dot   x   exp  -t  2     or  x   exp  -t  t

All the 3 first ways are identical  You have make sure that if t is a matrix you add   before using multiplication or the power   for matrix   t   1 2 3 2 3 4 3 4 5   tp t  t  x exp - t  2    y exp - t  t    z exp - tp      gives the results   x    0 3679    0 0183    0 0001 0 0183    0 0001    0 0000 0 0001    0 0000    0 0000  y    0 3679    0 0183    0 0001 0 0183    0 0001    0 0000 0 0001    0 0000    0 0000  z   0 3679    0 0183    0 0001 0 0183    0 0001    0 0000 0 0001    0 0000    0 0000   And using a scalar   p 3  pp p 2  x exp - p 2    y exp - p p    z exp -pp     gives the results   x    1 2341e-004  y    1 2341e-004  z    1 2341e-004
