import tensorflow as tf
#第一种计算方式
# a = tf.constant(2)
# b = tf.constant(3)
# with tf.Session() as sess:
#     print("a:%i" % sess.run(a), "b:%i" % sess.run(b))
#     print("a+b=%i"%sess.run(a+b))

#第二种计算方式
# a = tf.placeholder(tf.int16)
# b = tf.placeholder(tf.int16)
# add = tf.add(a, b)
# mul = tf.multiply(a, b)
# with tf.Session() as sess:
#     print("a+b=%i" % sess.run(add, feed_dict={a: 2, b: 3}))
#     print("a*b=%i" % sess.run(mul, feed_dict={a: 2, b: 3}))

#矩阵运算
mat1 = tf.constant([[2., 3.]])
mat2 = tf.constant([[2.], [2.]])
product = tf.matmul(mat1, mat2)
with tf.Session() as sess:
    print(sess.run(product))
