The reason for my question about C is that if C is merely a scalar, I believe your integrand is "separable" and its integral can be expressed as the product of two single integrals, each using 'trapz'. If C is an n x n array, then it would probably be necessary to use a 'trapz' call within anoth...
Example: integral(fun,a,b,'ArrayValued',true) indicates that the integrand is an array-valued function. Waypoints— Integration waypoints vector Integration waypoints, specified as the comma-separated pair consisting of 'Waypoints' and a vector of real or complex numbers. Use waypoints to indicate...
To perform double or triple integrations on an array of numeric data, nest function calls to trapz. Get I = trapz(y,trapz(x,F,2)) I = 680.2000 trapz performs the integration over x first, producing a column vector. Then, the integration over y reduces the column vector to a singl...
cumtrapz(Y,1)works on successive elements in the columns ofY. cumtrapz(Y,2)works on successive elements in the rows ofY. Ifdimis greater thanndims(Y), thencumtrapzreturns an array of zeros of the same size asY. Tips Usetrapzandcumtrapzto perform numerical integrations on discrete data se...
What I'm trying to tell matlab is to find F for each of the y-values listed. I want matlab to list the array of which y-values were used and the corresponding F for that y-value. As it is when I enter my code my F is 0. ...

Hi everybody, i'm trying to integrate/put in a double array of the size 16x16 to a cell array with the size 16x16. For example i want the value of the double array from (1,1) in the cell array on {1,1}.speed. Further down is my code so far. In the last lines i extract...
Z = cumtrapz(X,Y) computes the cumulative integralofYwithrespecttoXusingtrapezoidal integration. XandY must be vectorsofthe same length,orX must be a column vectorandY an array whose first non-singleton dimensionislength(X). cumtrapz operates across this ...

If tspan contains two elements [t0 tf], then t contains the internal evaluation points used to perform the integration. If tspan contains more than two elements, then t is the same as tspan. y— Solutions array Solutions, returned as an array. Each row in y corresponds to the solution at...
