Logical scalar values:
The MATLAB also has or and and operators which work element wise for the matrices:
These operators will compare any of the two vectors or matrices, as long as they are of similar size, element-by-element, and return a vector or matrix of similar size of logical 1's and 0's. The operators | | and && are only used with scalars, not matrices. For illustration,
>> v1 = [3 0 5 1];
>> v2 = [0 0 2 0];
>> v1 & v2
ans =
0 0 1 0
>> v1 | v2
1 0 1 1
>> v1 && v2
??? Operands to the || and && operators should be convertible to the logical scalar values.
As with numerical operators, it is significant to know that the operator precedence rules. Table shows the rules for the operators which have been covered faraway, in the order of the precedence.
Tracing of Square matrices: The trace of a square matrix is the addition of all the elements on the diagonal. For illustration, for the preceding matrix it is 1 + 6 + 11 + 16,
Technique to creating this structure: An alternative technique of creating this structure, that is not as efficient, includes using the dot operator to refer to fields in the
Finding sums and products: A very general application of a for loop is to compute sums and products. For illustration, rather than of just printing the integers 1 through 5, w
Finding products by for loop: an illustration, when 5 is passed to be the value of the input argument n, the function will compute and return 1 + 2 + 3 + 4 + 5, or 15: >> s
Replacing, Finding, and separating strings: There are numerous functions which find and replace the strings, or parts of strings, within the other strings and functions which
str2num function - String: The function str2num does the opposite; it takes the string in which a number is stored and converts it to the type double: >> num = str2num('123.
Execution steps: Whenever the program is executed, the steps below will take place: The script calcandprintarea starts executing. The calcandprintarea calls the readr
Example of Plotting from a Function: For illustration, the function can be called as shown below: >> y = [1:2:9].^3 y = 1 27 125 343 729
Simplification Functions: There are numerous functions which work with expressions, and simplify the terms. Not all the expressions can be simplified, but the simplify functio
I have a 400x2 vel.dat and 20x2 xy.dat file, how can i plot a streamslice graph on matlab with this two files.
