I have a string matrix i.e.

A=["abcd",.....,"efghijk";...
   .   ...
   .   ...
   .   ...
"lm",......, "opkq"];

How to concatenate easily the rows of this matrix to get the result:

"abcdefghijk"

.

"lmopkq"

as a column vector?

A=["abcd","efghijk"; "lm", "opkq"]
A = 2×2 string array
    "abcd"    "efghijk"
    "lm"      "opkq"   
B = A(:,1) + A(:,2)
B = 2×1 string array
    "abcdefghijk"
    "lmopkq"

The more general solution (independent from number of rows or columns of your input is:

A=["abcd","efghijk", "1111"; "lm", "opkq", "2222"; "fdds<jgf", "dfkjf", "ldfkj"; "<ksajfjf", "fjjf", "fkkgfkdsw43"]
A = 4×3 string array
    "abcd"        "efghijk"    "1111"       
    "lm"          "opkq"       "2222"       
    "fdds<jgf"    "dfkjf"      "ldfkj"      
    "<ksajfjf"    "fjjf"       "fkkgfkdsw43"
B = join(A,'',2)
B = 4×1 string array
    "abcdefghijk1111"
    "lmopkq2222"
    "fdds<jgfdfkjfldfkj"
    "<ksajfjffjjffkkgfkdsw43"

ERASE is superfluous**, simply specify both the delimiter and dimension:

A=["abcd","efghijk", "1111"; "lm", "opkq", "2222"; "fdds<jgf", "dfkjf", "ldfkj"; "<ksajfjf", "fjjf", "fkkgfkdsw43"];
B = join(A,'',2)
B = 4×1 string array
    "abcdefghijk1111"
    "lmopkq2222"
    "fdds<jgfdfkjfldfkj"
    "<ksajfjffjjffkkgfkdsw43"
