WebMATLAB can perform integer arithmetic on the following types of data: Integers or integer arrays of the same integer data type. Arithmetic operations yield a result that has the same data type as the operands: x = uint32 ( [132 347 528]) .* uint32 (75); class (x) ans = 'uint32'

WebMATLAB provides an int command for calculating integral of an expression. To derive an expression for the indefinite integral of a function, we write − int (f); For example, from our … WebI = ∫ 3 x 2 d x = x 3 + c. where ‘c’ is a constant. A definite integral for the same equation must have defined limits. For example, we can integrate the above equation with limits [-2, 2] as …

WebDec 1, 2011 · You will have to define the function x (t). If you were expecting it to solve for a generic function x (t), without defining it, you're using the wrong tool. You should probably use Mathematica/Maple. Remember, MATLAB's symbolic math toolbox is rudimentary.
