I assumed newline (and e.g. output to file) because of the way the question was formulated/structured, but this is a good point.Evaluate String as Symbolic Expression. Evaluate the string 'sin (pi)' . str2sym returns the expected result. str2sym ('sin (pi)') ans = 0. str2sym assumes the = operator represents an equation, not an assignment. Also, str2sym does not add the variables contained in the string to the workspace. Show this behavior by evaluating 'x^2 = 4'.The undocumented datenummx exists since Matlab 5.3 to (at least) 2016b and it is the fast core under the smart and intelligent datenum. 3 Comments.

I …The solution is simple: use str2num to convert the table of strings to numbers. As an aside, you don't need cell2mat for a single element of the table, just index in with curly braces, rather than parentheses. c (4,2) will return a single cell containing the string '5'; c {4,2} will return the contents of that cell - the string itself. 4 Comments.

M = str2double (C) The cell2mat function converts a cell array of character vectors to a character array, and only if all the character vectors have the same length. cell2mat also preserves the data type of the contents of the cells, so it does not convert characters to numbers. If you need your code to be fast, then use the following code instead.
