Extend a string within a for loop by values from switch case
显示 更早的评论
This switch case works in c. With each pass, the loop finds a letter and assigns it to a binary sequence. The nice thing is, each new binary sequence is simply added (by: +=) to an existing string. Does this also work in matlab?
for (int i = 0; i < sizeInput; i++) {
switch (inputText[i]) {
case ' ':
outputText+= "00000";
break;
case 'A':
outputText+= "00001";
break;
case 'B':
outputText+= "00010";
break;
}
}
For example the inputText is: AB BA, the result should look like: 0000100010000000001000001
I hope you can help me with this.

No, MATLAB doesn't support Augmented addition, (using +=)
However, you can obtain the same result with a variable, x=x+1; and use dec2bin(x).
If you add strings together in MATLAB, it will give a double (default MATLAB numeric format) output corresponding to the ASCII codes.

Forget about C.
The MATLAB approach is to work with vectors and matrices (which is where the name MATLAB comes from):
inp = 'AB BA';
vec = ' AB';
rpl = ["00000","00001","00010"];
[X,Y] = ismember(inp,vec);
out = join(rpl(Y(X)),'') % string scalar
out = [rpl{Y(X)}] % char vector
