Code Previously Worked, Now keep getting "Unexpected Matlab Expression"..

function [t,x,u] = vehicleModel(0,10)

[t,u] = ode45(@vehicleAccel, [10], 0, options);

x = cumtrapz(t,u);
return

The Code above is a function file which links to two other functions, and all together are run off another script. Earlier in the day, the file worked, and I was able to plot a graph off it. Now, it doesnt work, and the only thing I changed, was a value assigned to a variable in a separate function. How can I resolve this? Matlab is saying the 0 in the first line is what is causing the problem.

Answer 1

[Adam]

Have you defined a variable called vehicleModel?

If so Matlab will attempt to index into that variable with your arguments rather than call the function

[Tom Byrne]

vehicleModel is the name of the function. Its then called into the last script I use to plot two variables that are found from the 3 functions. At least that was my understanding of how it worked? The problem is, is that it worked literally 3 hours ago.

Answer 2

[Sean de Wolski]

function vehicleModel(0,10)

A variable name must start with a letter, and a function must take in variables.

function vehicleModel(q,k)

Will work since q and k are valid variable names.

The values of q and k could be anything
