MATLAB Online에서 열기 I guess you figured it out since you accepted the answer (remove the division by N), but here is the answer assuming N is the length of the x vector: FI = sum(abs(diff(x))); or more accurately, assuming we just want to sum up to N and we have ...

indexOfMaxSlopeDiff = 167 Left Equation: y = 0.003 * x + 4.042 Right Equation: y = 0.295 * x + -5.968 so you can see that at index 167, which is x=34.3, is the best place to split the curve up into two linear segments, and the e...
Open in MATLAB Online I have an integral that cannot be evaluated symbolically. When I try to do it numerically I want to keep some symbols in the result (to have an output like 10*x1+0.5*x3 where x1 and x3 are symbols) because in a further step I want to build a syste...
Open in MATLAB Online Hi, I used "diff" to differentiat an symbolic expression (which is a 2*1 matrix in terms of one variable "p1" )and I get the result is iftrue % (993145510909945291290970062799168703243609151945831132541235246491728972506726400000*p1^24)/(11*(66209700727329686086064670853277913549573943...

matlab syms x Once we have defined the symbolic variables, we can use the built-in symbolic functions to perform operations and calculate derivatives. The most commonly used function for symbolic differentiation isdiff. This function takes the derivative of an expression with respect to a specified...
