How to assign the result of a row deletion operation to a new matrix?

I have a 10X10 matrix, from which I delete the row 3 applying A(3,:)= [] . I want to save the original matrix and have the new matrix with a deleted row assigned to a new variable C. Now how do I assign this result to a new matrix C?

I do C= A(3,:)=[] but it is obviously wrong.

Thank you!

I would do something like this —

A = magic(10)                                   % Save Original

A = 10×10

92 99 1 8 15 67 74 51 58 40 98 80 7 14 16 73 55 57 64 41 4 81 88 20 22 54 56 63 70 47 85 87 19 21 3 60 62 69 71 28 86 93 25 2 9 61 68 75 52 34 17 24 76 83 90 42 49 26 33 65 23 5 82 89 91 48 30 32 39 66 79 6 13 95 97 29 31 38 45 72 10 12 94 96 78 35 37 44 46 53 11 18 100 77 84 36 43 50 27 59

C = A;                                          % Copy 'A' To 'C'
C(3,:) = []                                     % Delete Row 3 From 'C'

C = 9×10
