functions of variables with matrices
I am trying to make a function of a variable with sage for example:
f(x) = sin(x) f(x+y)
However if It is in a matrix this no longer works:
f(x) = matrix([[sin(x)],[cos(x)]]) f(x+y)
Is this not possible or am I missing something to make this work?
I am using sage 7.3 on Ubuntu 16.04 with the aims ppa.
