How to handle this error: Brace indexing is not supported for variables of this type.

The error says as :::

Brace indexing is not supported for variables of this type.

Error in lab_3Q2>huffman_encode (line 122)

[prob, symb] = hist(rl_mat{i, j}(:), unique(rl_mat{i, j}));

Error in lab_3Q2 (line 21)

[code, dict] = huffman_encode(run_len);

where rl_mat is a string of double precision array i'm passing

Can someone please rectify the error.

But the function needs a cell array not a double precision array

[Sanjana]

So, sir is there any way i can use the function for a double precision array. Or can i convert it to a cell array?

Thanks in advance.

It looks to me as if you could pass in your double precision array wrapped in a cell array, like

{YourArray}

Hi Sanjana,

I understand that you are getting the "Brace indexing is not supported for variables of this type." error.

You are using the "hist" function, which accepts vector or matrix input. Therefore, I would recommend you to double-check the type of value you are passing to the "hist" function.

Refer the following MathWorks documentation to know more about the "hist" function.

Referring to the following MATLAB Answer might be helpful to you.

I hope this resolve your query.
