The natural logarithm function in MATLAB is log(). To calculate the natural logarithm of a scalar, vector or array, A, enter log(A). Log(A) calculates the natural logarithm of each element of A when A is a vector or array.F = symsum (f,k,a,b) returns the symbolic definite sum of the series f with respect to the summation index k from the lower bound a to the upper bound b. If you do not specify k, symsum uses the variable determined by symvar as the summation index. If f is a constant, then the default variable is x. symsum (f,k, [a b]) or symsum (f,k, [a; b ...This example uses the filter function to compute averages along a vector of data.

If fscanf cannot match formatSpec to the data, it ...Request Numeric Input or Expression. Request a numeric input, and then multiply the input by 10. prompt = "What is the original value? " ; x = input (prompt) y = x*10. At the prompt, enter a numeric value or array, such as 42. x = 42 y = 420. The input function also accepts expressions. For example, rerun the code. In this code, you can create your own vector by prompt "m" value. For example, if you type m= 5, you will have 1x5 vector. Then, you can start to prompt your own integers. If you want to create a matrix with the same method, you use this code: Theme. Copy. n = input ('n= '); m = input ('m= '); for i= 1:n.An Input processing parameter on the block determines whether each element or column of the input signal is a channel. Some blocks, such as the digital baseband modulation blocks, can produce multiple output values for each value of a scalar input signal. ...
