MATLAB provides themax()function used to find the maximum value in an array or matrix. It has different modes for processing data and can be helpful in finding the maximum value in a variety of scenarios. In this tutorial, we have learned the usage of themax()function with examples. By ...

You can use for loop or while loop for finding out the maximum or minimum element in the array without using any built-in functions.I
If sparse, its indices and nonzero maximum elements If a structure or an object, the number of fields and field names To access the mxArray structure, use functions in the C or Fortran Matrix APIs. These functions allow you to create, read, and query information about the MATLAB data in...

If you convert a number that is larger than the maximum value of an integer data type to that type, MATLAB sets it to the maximum value. Similarly, if you convert a number that is smaller than the minimum value of the integer data type, MATLAB sets it to the minimum value. For exampl...
