[theano]入門-變數相加、矩陣聲明

標籤：

#作為python新手，可能學習的東西比較多，注意如果兩個矩陣相乘的話，跟matlab區別還是挺大的
#!/usr/bin/env python# coding=utf-8#格式一般用import ss as dimport theano.tensor as Tfrom theano import functionimport numpy as np#聲明變數x=T.dscalar(‘x‘)y=T.dscalar(‘y‘)z=x+yf=function([x,y],z)#call the functionf(2,3)print f(2,3)#declare the varalblex=T.dmatrix(‘x‘)y=T.dmatrix(‘y‘)z=x+yf=function([x,y],z)c=f([[1,2],[3,5]],[[1,3],[3,5]])print c[0,0]#shape function will return the size of a arrayd=np.shape(c)print da=3b=2#** means micic=a**2print ca=T.vector()out=a**10f=function([a],out)print f([1,2,3])
