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.
The esophagus is the muscular tube that carries food, and liquids from your mouth to the stomach. You may not be aware of your esophagus until you swallow something too large, too hot, or too cold. You may also notice it when something is wrong. You may feel pain or have trouble swallowing. The most common problem with the esophagus is GERD (gastroesophageal reflux disease). With GERD, a muscle at the end of your esophagus does not close properly. This allows stomach contents to leak back, or reflux, into the esophagus and irritate it. Over time, GERD can cause damage to the esophagus. Other problems include heartburn, cancer, and esophagitis.
