I've seen several answers to this question, but none appear to work. The following example taken from another question, when pasted directly, gives this error message:
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.
Error in legend>process_inputs (line 547) strings = cellstr(argin{n});
Error in legend>make_legend (line 306) [autoupdate,orient,location,position,children,listen,strings,propargs] = process_inputs(ha,argin); %#ok
Error in legend (line 259) make_legend(ha,args(arg:end),version);
Error using cellstr (line 44) Element 6 is not a string scalar or character array. All elements of cell input must be string scalars or character arrays.
Error in legend>process_inputs (line 547) strings = cellstr(argin{n});
Error in legend>make_legend (line 306) [autoupdate,orient,location,position,children,listen,strings,propargs] = process_inputs(ha,argin); %#ok
Error in legend (line 259) make_legend(ha,args(arg:end),version);
Error in Untitled (line 9) legend(lgd);:
time = linspace(0, 2*pi); % Create Data
beta = 1:5; % Create Data
y = sin(time(:)*beta); % Create Data
for beta_val = beta
plot(time, y(:,beta_val));
hold on
lgd{beta_val} = sprintf('beta = %0.0f', beta(beta_val));
end
legend(lgd);

I had the same error. When I search, I reach your topic. Your code worked well on my MATLAB version; which is R2017b. I don't know if you're still having the problem. If you are,
- try editing the last line as
legend(string(lgd));
- be sure your whole script is not within a function as cell array lgd won't be held within the function.
