I have a vector which coul look like this: A = [2 25 1017]. I want to use these numbers in a legend of my plot. Apparently I need to convert them from double into cellstr. Thats what I get out of the error message: Cell array argument must be a cell array of character vectors. How do I convert double into cellstr?
Thanks in advance

Use the compose function (introduced in R2016b) —
A = [2 25 1017];
Ac = compose('%d',A)
Ac = 1×3 cell array
{'2'} {'25'} {'1017'}
.

Hi Dominic, You can refer to the below code to convert double to cell array.
A = [2 25 1017];
A_str = arrayfun(@(x) num2str(x), A, 'UniformOutput', false)
A_str = 1×3 cell array
{'2'} {'25'} {'1017'}
This code snippet uses arrayfun to apply the num2str function to each element of the array A, converting each number to a string. The 'UniformOutput', false argument is used to output the results in a cell array, which is necessary for the legend function in MATLAB.
