For example, let’s make a matrix of zeros of size 3-by-3. Even a single number is stored as a matrix. Finally, I want two things where I need some help: 1) replace the 'NaN' with the original numbers marked with '#', for instance '# 2. With the help of a 2D array, we can manipulate the matrix, the structure of the matrix contains the rows and columns and each value from the matrix contains the row index and column index. An array having more than two dimensions is called a multidimensional array in MATLAB. ColName Value = Col1 Val1 Col2 Val2 I have my ColName in colheaders which is a 1xM cell (of strings) and my values in predRes which is a 1xM Matrix (of double). Any particular element can be accessed using indexing in MATLAB.

To display some text and a matrix, you can use two disp statements. I wish to extract the first and third row as numbers to be assigned to a numerical matrix, while extracting the second row as a row of strings, which are to be assigned to another matrix. The indexing in arrays in MATLAB is the same as mathematics.

To free a string mxArray, call mxDestroyArray. str (1,2) ans = "Gemini" Access the third column. One of the new features I love in R2016b is string arrays, which give you a new way to handle text in MATLAB in addition to the familiar character arrays and cell arrays of character vectors. The first argument of the strfind() function is the string from which you want to find the occurrences of a substring, and the second argument is the string or character you. The first issue is to multiple these two matrices after converting them to numerical with str2num function.
