回答： Jan 2022-10-22

I have a cell array A =

{ a1 = 1}

{ a2 = 2}

{ a3 = 3}

{ a4}

{ a5}

{ a6 = 6}

I have used a split command to split the cell A into two cells based on the delimiter ( B = split(A ,'='); )

I get an error

Element 4 of the text contains 0 delimiters while the previous elements have 1. All elements must contain the same number of delimiters.

I want the output to be

B =

{a1} {1}

{a2} {2}

{a3} {3}

{a4}

{a5}

{a6} {6}

Can anyone help me in this ?

That's not MATLAB code. See:

A = 
Invalid expression. Check for missing or extra characters.
{ a1 = 1}
{ a2 = 2}
{ a3 = 3}
{ a4}
{ a5}
{ a6 = 6}

Please either give code to generate A properly or attach A in a .mat file. I also have no idea what you mean for B so create a B and attach it in the .mat file also so we can see what it really is.

Sorry for my vague explanation above. Below would be the code

A = {'a1 = 1'; 'a2 = 2'; 'a3 = 3'; 'a4 ';'a5 ';'a6 = 6';'a7 = 7'};

B = split(A,'=');

and the error

Error using split (line 99)

Element 4 of the text contains 0 delimiters while the previous elements have 1. All elements must contain the same number of delimiters.

You want the output:

B = 
{a1} {1}
{a2} {2}
{a3} {3}
{a4}
{a5}
{a6} {6}

This is not possible. A cell matrix is still a matrix and this means, that all rows must have the same number of elements. This is the cause for the split function to fail.
