IfAis a cell array of character vectors, thenBis a string array that has the same size. IfAis a character array with multiple rows, then the columns ofAare concatenated andBis returned as a string scalar. For example, the 3-by-2 character array['Xx';'Yy';'Zz']is converted to"XYZxy...
= str2num(txt)converts a character array or string scalar to a numeric matrix. The input can include spaces, commas, and semicolons to indicate separate elements. Ifstr2numcannot parse the input as numeric values, then it returns an empty matrix. Thestr2numfunction does not convert cell array...
