 I try to compute matrix multiplication for matrix with entries likes 1/sqrt(2) But any my tries finished with error (wolfram can not understand me....) I tried in W|A: {{1/Sqrt[2]}, {1/Sqrt[2]}}.{{1/Sqrt[2], 1/Sqrt[2],0}} I need matrix 1x3 but 3x1 is correct {{1/Sqrt[2], 1, 2}}Please give me some idea about it

 Ok I want to compute {{1/Sqrt[2]}, {1/Sqrt[2]}}.{{1/Sqrt[2], 1/Sqrt[2],0}} but Wolfram says me wrong dimensions I want to compute 21 . 13 matrices
 Ok I want to compute {{1/Sqrt[2]}, {1/Sqrt[2]}}.{{1/Sqrt[2], 1/Sqrt[2],0}} but Wolfram says me wrong dimensions I want to compute 2*1 \cdot 1*3 matrices
 Woiks for me. In[3]:= {{1/Sqrt[2]}, {1/Sqrt[2]}}.{{1/Sqrt[2], 1/Sqrt[2], 0}} Out[3]= {{1/2, 1/2, 0}, {1/2, 1/2, 0}}
