How do you find the maximum value in an array in MATLAB?

The max() function in MATLAB is specifically designed to find the maximum value within an array. It efficiently computes the maximum by comparing each element of the array, making it a straightforward and reliable choice for this operation. When you apply max() to an array, it returns the largest value, whether your data is organized as a vector or a matrix.

The other options presented are not valid functions in MATLAB for this purpose. For instance, highest(), maximum(), and peak() do not exist as built-in functions in MATLAB, making them ineffective for finding maximum values in an array. Therefore, knowing that max() is the correct and only function suited for finding the maximum value underscores its significance as a fundamental tool in MATLAB for this computational task.
