Arun: Yes, it will simply fill in NaN for missing numeric values and '' for missing text. Thank you for your reply. When I try this I actually get an error that the. However I used dlmread with the original text file and everything worked. Arun: Without seeing what your file looks like, I'm afraid I can't help further.
Glad you found a solution in dlmread , though. If you really want to process your file line by line, a solution might be to use fgetl : Open the data file with fopen Read the next line into a character array using fgetl Retreive the data you need using sscanf on the character array you just read Perform any relevant test Output what you want to another file Back to point 2 if you haven't reached the end of your file.
Hope this will help. Adrien Adrien 1, 9 9 silver badges 12 12 bronze badges. You cannot read text strings with csvread. Steve Pitchers 6, 5 5 gold badges 38 38 silver badges 38 38 bronze badges. Adrian Adrian 3, 18 18 silver badges 22 22 bronze badges. Hope it will help! From the documentation: " csvread will be removed in a future version. Use dlmread instead.

Reading CSV file using function. Show older comments. Sivateja Maturu on 28 Jan The first syntax is used for files that contain only numerical values, while the latter two options enable data to be selectively chosen from a sequence based on pre-identified criteria.
The key to theory application is practice. Let us now delve into one option that we can utilize, in order to ensure that the skillsets are engrained in our brains! In this initial example, the first thing we are going to do…is start with a fresh command page. MATLAB, as a license-based system enables the user to log in using either an industry based, or educational system based login.
Once you have logged in, the following should be your screen:. With a fresh command page open, we will go ahead and enter data from a pre-generated.
The file data is highlighted as follows:. With MATLAB, the user has the option to read the data, as well as carry out a few calculations pertaining to the data that was collated. Freestyle, but in the process of saving as a. The screen image is highlighted below:. Based on what was indicated in the preamble under the definition of the code, there is an alternate path that we will have to take in order to achieve the desired objective.
While alternate code is a possibility, the ribbon helps us to achieve the same objective. As with all things in life, the road may not always be a straight line, but you get there eventually. Before you start worrying, let us now explore the section of the command window known as the ribbon.
In most of the activities we have done, the exercise tends to focus on straight code entry. In this instance, we can attempt to use some of the alternative built in paths, and see what the system will enable us to do. Looking from the left to the right you see that there are various options for you to tap into as users.
The first option is for you to enter a new script, or enter a new live script. This segment will be helpful in the future. Scrolling to the right, there is an Import Data tab.
Go ahead and press this button. The following is what will appear on your screen. The following subsequent screen will appear.
