Select the worksheet, drag and drop the mouse over the range you want, and click OK. This syntax is supported only on Windows computers with Microsoft Excel software installed. The xlsread function returns the text fields in cell array txt, both the numeric and text data in cell array raw, and the second output from processFcn in array custom.
Doesn't seem to make much sense if the missing values of the shorter observations are scattered, so simply augment the shorter with NaN or some other indicator value based on length of longest before the concatenation operation.
Or, of course, while a little more work, you could loop through for 1: Obviously, the first solution is simpler. Of course, whether the result makes any sense or not is another issue You will have to make sizes commensurate with missing value indicators if you insist on the concatenation route.
If all were numeric as would be presumed from original variables names, then you could have two operations; concatenate the subsections of same size and fprintf them, then fprintf the subsection of longer elements as a second array.
But, for the mixed data you'll have to loop irregardless unless you were to import to a table again will need missing value indicators, though. Then writetable might be able to deal with it for you although you'd have to convert the numerics to string inside the table methinks to be able to get the blank rows; missing values as NaN for numbers would still show up.
Of course, then the output would contain NaN which is probably not what want. For the second example, it takes some more effort.If you don't know the number of elements in the last two arrays on the line, I'd use fgetl() to read it in line by line and write a custom routine to parse the line.
How do I convert an image to text using MATLAB coding? Update Cancel. How can I convert an image into binary data to store it in a text file using MATLAB? How can I restore it again from the text file?
How do I write a MATLAB code for all image transformations like . All variables of all data types in MATLAB are multidimensional arrays. A vector is a one-dimensional array and a matrix is a two-dimensional array.
We have already discussed vectors and matrices. In this chapter, we will discuss multidimensional arrays.
However, before that, let us discuss some. The ability to save a cell array of strings to a text file with one function is not available in MATLAB but can be implemented in a number of methods. You will need to use low-level file I/O routines to . Comma-separated value (CSV) files are text files that contain data separated by commas and line breaks.
A matrix, for example, might be stored in a CSV file containing as many lines as there are rows, each line containing the row's elements separated by commas.
The first call to fprintf prints header text x and exp(x), Write an array of data, A, to a file and get the number of bytes that fprintf writes. A = magic(4); fileID = fopen such as a text conversion for a numeric value, MATLAB overrides the specified conversion, and uses %e.
