A = ["C"; "A"; "E"; "F"; "I"]
A = 5×1 string array
    "C"
    "A"
    "E"
    "F"
    "I"
B = ["A", 1;"B", 34;"C" 56;"D" 32;"E",11;"F",8;"G", 7;"H",9;"I" 77]
B = 9×2 string array
    "A"    "1" 
    "B"    "34"
    "C"    "56"
    "D"    "32"
    "E"    "11"
    "F"    "8" 
    "G"    "7" 
    "H"    "9"

在 MATLAB Online 中打开

A = ["C"; "A"; "E"; "F"; "I"]
A = 5×1 string array
    "C"
    "A"
    "E"
    "F"
    "I"
B = ["A", 1;"B", 34;"C" 56;"D" 32;"E",11;"F",8;"G", 7;"H",9;"I" 77]
B = 9×2 string array
    "A"    "1" 
    "B"    "34"
    "C"    "56"
    "D"    "32"
    "E"    "11"
    "F"    "8" 
    "G"    "7" 
    "H"    "9" 
    "I"    "77"
[ism,idx] = ismember(A,B(:,1));
assert(all(ism))
result = B(idx,:)
result = 5×2 string array
    "C"    "56"
    "A"    "1" 
    "E"    "11"
    "F"    "8" 
    "I"    "77"
