Convert cell to string

I have a cell (721*1), each cell composed by a different number of string, for example, the first cell is a (1*20) string. I want to convert this cell to string. when I use string function, it reported an error as "Conversion from cell failed. Element 1 must be convertible to a string scalar.". I have no idea why it can't convert as the string function described in Matlab.

So what is that conversion from cell array to string supposed to do? What do you want as an output?

Assuming it's a 1xN string array that is simply the concatenation of all the string arrays in your cell array, then:

sarray = [A{:}]

The above will fail if at least one string array in any cell does not have the same number of rows as all the other string arrays.

Hi Thanks for your answer. I want a string array. I think this way may be more easy to understand: I have a cell, but have different dimensions. some has 1xN, some are 1xM. I try with strsplit and your way. those function can convert 1xM single cell to a string array. But they can't concatenate to a string array because of the inconsistent dimensions.

Still have no idea what you want. You tell use what doesn't work but not what the result should be. Let's be concrete. Given the cell array:

c = {["a", "bbbb"], ["cc", "dddd", "e"]}  %cell array with string arrays of different size

What do you want as output? Exact answer in valid matlab syntax please.

strarray=["a","bbbb";"cc","dddd","e"]

That is not possible and what you wrote would produce an error in matlab. string arrays like all arrays must have the same number of elements in each row.

You cannot vertically concatenate string row vectors of different size. You can however horizontally concatenate them and my original answer did just that.

Yes, I understand now. Thanks for your time. Really appreciated.

What happens when you do?

cellstr()

[Fei Li]

It reports an error "Error using cellstr (line 44) Element 1 is not a string scalar or character array. All elements of cell input must be string scalars or character arrays."

[madhan ravi]

I think the contents in your cells are strings

[Fei Li]

Yes, they are strings have different dimensions.

[madhan ravi]

If they are strings why do you want to convert them?

[Fei Li]

but they are in a cell. I want a string array. Is that possible? anyway, thanks to all your help.
