The arrays may be of a. di erent data type. I Use a MATLAB cell array. In a cell array, each element of. the array is another array. We are generating arrays recursively. and they do not need to be of the same data type. First we work with structures.
Updated February 18, 2016. A fecal occult blood test (FOBT) is a non-invasive way to screen for blood in your stools, which can be a symptom of colon cancer. If a FOBT finds blood in your stools, you will be referred for further colon cancer screening, such as colonoscopy or flexible sigmoidoscopy.
Get the facts. Annual stool testing works by finding colon cancer early, when it may be most treatable. It looks for invisible blood in the stool (poop), which can be a sign of cancer. Since blood can also come from hemorrhoids or other causes, youâll need to follow up with a colonoscopy if you get a positive result. When repeated every year, the stool test is shown to save lives from colon cancer.
