For example, consider a MAT-file with variables height, width, and length. If you load these variables in a function such as findVolume, MATLAB interprets the reference to length as a call to the MATLAB length function, and returns an error. function vol = findVolume(myfile) load(myfile); vol = height * width * length; end. Error using length Not enough input arguments.
This is an inflammation of the esophagus that causes swelling and makes it more difficult to swallow. When food gets stuck, itâs called an esophageal bolus impaction. How can I tell that food is stuck in my esophagus? It occurs while eating a meal. You may experience pressure in your chest.
Injury to the esophagus may be due to a number of causes. A foreign body that enters the esophagus (like a fish bone or small sharp toys ingested by infants) can lodge in the esophageal lining or cause tears. Very hot foods or drink may also cause trauma to the esophageal lining.
