Storing Wav files in an array

Sry im new to matlab been using it only for homworks

So i was trying to divide a .wav file into 7 parts and store them in a array of size 7 got this error

CODE

[tel,fs]=audioread('tel.wav');

n=7;

d=floor(length(tel)/n);

for i=1:n

a[i]=tel(1+(i-1)*d:(i*d));

sound(a[i]);

end;

ERROR

Invalid expression. When calling a function or indexing a variable, use

parentheses. Otherwise, check for mismatched delimiters.

As the error message states, MATLAB uses parentheses for indexing. You used square brackets.

Hi thank you

but now i get this error

Unable to perform assignment because the indices on the left side are not

compatible with the size of the right side.

Error in odev2 (line 9)

a(i)=tel(1+(i-1)*d:(i*d));

[Stephen23]

You get that error because you are trying to assign multiple elements into one element of an array. That will not work.

Is it required to store all of the data in array a ? If you do not need the data to be available after the loop then just get rid of the indexing entirely. Otherwise you will need to use e.g. a cell array:
