MATLAB: Is there the more elegant way to do this

Question

I have 10 matrices(10*24 size each) named A1,A2,,,,A10.Now i want this

E1=sum(A1); 
E2=sum(A2); 
till E10=sum(A10);

thus E1,E2,,,,,E10 each matrices size of 1*24 . so there is another way to write in short code ?

Hi Mukesh Kumar

Elegance like beauty lives in the eyes of the observer, so while some people abhor the command evalin, I consider it's a really powerful and elegant option to simplify the generation of variables.

1.

Simulating data

A1=randi([-10 10],3)
A1 =
      -2     4   -10
       3   -10    -8
      -7    -5     7
>> A2=randi([-10 10],3)
A2 =
       4   -10     6
      -4    -1     6
       9    -2    -7
>> A3=randi([-10 10],3)
A3 =
       0     4     4
      -1     5     3
       3    -5    -7

2. Code that writes code

for k=1:1:3
str1=['E' num2str(k) '=sum(A' num2str(k) ')'];
evalin('base',str1)
end
E1 =
      -6   -11   -11
E2 =
       9   -13     5
E3 =
       2     4     0
