You may use fieldnames to get the data from the struct and then iteratively display the data using getfield function. For example: structvariable = struct ('a',123,'b',456,'c',789); dataout = zeros (1,length (structvariable)) % Preallocating data for structure field = fieldnames (a); for i = 1:length (structvariable) getfield (structvariable ... how much do you make at lowe's 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.intout = bitset (A,bit) returns the value of A with position bit set to 1 (on). intout = bitset (A,bit,assumedtype) assumes A is of type assumedtype. intout = bitset (A,bit,V) returns A with position bit set to the value of V. If V is zero, then the bit position bit is set to 0 (off). If V is nonzero, then the bit position bit is set to 1 (on).MATLAB constructs the double data type according to IEEE ® Standard 754 for double precision.
