C1 = 2×1 cell array {[ 1]} {[0.0000 + 1.0000i]} Callarrayfunand access the elements ofA. Assign its values to a cell array. WhenarrayfunaccessesA(1), it treats that value as a complex number and assigns it toC2
B = arrayfun(func,A) applies a function func to each element of a gpuArray A and then concatenates the outputs from func into output gpuArray B. B is the same size as A and B(i,j,...) = func(A(i,j,...)). The input argument func is a function handle to a MATLAB function...
IfAis a multidimensional array, thenresize(A,m)pads or trimsAto the size specified bymalong the first dimension whose size does not equal 1. Ifmis a vector, then each element inmrepresents the size of the corresponding dimension inB.
Data Types:single|double|int8|int16|int32|int64|uint8|uint16|uint32|uint64|logical|char Tips Most arithmetic operations involving logical arrays return double values. For example, adding zero to a logical array returns a double array.
Array Creation To create an array with four elements in a single row, separate the elements with either a comma (,) or a space.(使用逗号或空格分离。 a = [1 2 3 4] returns a = 1 2 3 4 This type of array is arow vector. ...
Logical values where logical 1 (true) indicates a breakpoint in the corresponding element of the input data. If bp contains logical values, it must be the same length as the sample points. Breakpoints are useful when you want to compute separate trends for different segments of the data. Dat...
To perform element-wise multiplication rather than matrix multiplication, use the.*operator: p = a.*a The matrix operators for multiplication, division, and power each have a corresponding array operator that operates element-wise. For example, raise each element ofato the third power: ...
asx_date Required. A date that represents an ASX trading date switch_dates Optional. An optional list of two or more dates to align the ASXtrading dates with the YAHOO data dates. The list can be either a range of cells that contain the dates or an array constant of the ...
max Returns largest element. min Returns smallest element. prod Product of each column. reshape Changes size. size Computes array size. sort Sorts each column. sum Sums each column. eye Creates an identity matrix. ones Creates an array of ones. zeros Creates an array of zeros. cross Computes...
