c = 'MATLAB' Converting Unicode values also allows you to include special characters in text. For instance, the Unicode value for the degree symbol is 176. To addchar(176)to a string, useplus. deg = char(176); temp = 21; str ="Temperature: "+ temp + deg +"C" ...
By "arrow" I meant row. There are two problems with my results; first the rows of matrix A are not assigned to the variables I created previously (A1, A2 & A3). Second, even after obtaining matrix A, I cannot perform arithmetic operations for each element...
There are several points to mention actually. You have to differentiate numeric arrays from cell arrays (many posts or help pages are available for that). Numeric arrays can only contain numbers, homogeneous in type/class (e.g. only
X = 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. If str2num cannot parse the input as numeric values, then it returns an empty matrix. The str2num function does not convert...
