The trapz in MATLAB plays a vital role in integration calculations applied in real-time applications. In order to perform trapz function on double integral expression, the function is called in the nested loop as demonstrated in the below example:Įxample #5 – Real-time application of trapz The integration function trapz can also be used to perform double integral i.e integration in the format: Example #4 – Multiple numerical integrations The resultant output is a column vector having an integration result for each row. Trapz is executed on each row of the input numeric ‘Y’ as the value for ‘dim’ is set to 2. The rows in input numeric data ‘Y’ is obtained from velocity data taken at 3 different trials. The point spacing is obtained by matrix ‘X’ which indicates that the trapezoids are formed non-uniformly.
The below code is written to call the trapz function on the input numeric data ‘Y’ with non-uniform point spacing values defined by ‘X’ with the value of ‘dim’ as ‘2’. This operation can be executed by applying the syntax Q = trapz(Y, X, dim) in the trapz function implementation in the MATLAB code. The below code is written to call trapz function on input numeric data ‘Y’ having point spacing value of pi/10.Įxample #3 – Numerical integration with non-uniform spacing This operation can be executed by applying the syntax Q = trapz(Y, X) in the trapz function implementation in the MATLAB code. The below code snippet is written to execute trapz operation on input numeric ‘Y’ as f(x)= 10*2^x.Įxample #2 – Numerical integration with Non-Unit spacing This operation can be executed by applying the syntax Q = trapz(Y) in the trapz function implementation in the MATLAB code. Here are the following examples mention below: Example #1 – Numerical integration with Unit spacing
